serial: bfin: Flip the jtag serial console to CONFIG_SERIAL_MULTI

Rework the emulation of serial console via JTAG from simple ad-hoc
implementation of serial port routines to CONFIG_SERIAL_MULTI and
enable CONFIG_SERIAL_MULTI unconditionally for blackfin.

In order for the JTAG serial console to take precedence over all
other serial ports available in system, implement override for
default_serial_console call returning this JTAG serial console.

This brings in a bit of a growth of size, but eventually will allow
us to unconditionally enable CONFIG_SERIAL_MULTI throughout the whole
U-Boot and maintain only one serial subsystem.

serial: zoom2: Remove zoom2 serial prototypes from serial.h

Remove the prototypes for zoom2_serial_deviceN from serial.h . This
can't be done right away, as they are referenced from the zoom2
config file. Therefore, adjust the code so the config file only
specifies number of the port. Then, replace the simple return in
default_serial_console() with a switch across possible values, which
returns the zoom2_serial_deviceN . With such adjustment in place,
the exported prototypes in serial.h can be safely removed.

serial: s5p: Move serial registration from serial_initialize()

Move the registration of s5p_serialN_device ports from default
serial_initialize() into driver specific function called from
serial_initialize(). This slims down the serial_initialize() call
to a bare tracker of all possible serial port registration routines
in U-Boot.

The newly implemented s5p_serial_initialize() function, which is
implemented inside of the serial_s5p driver allows encapsulation
of s5p_serialN_device within the serial_s5p driver itself.

Also, remove the exports of s5p_serialN_device from include/serial.h
as they are no longer needed. This is simply because the implementation of
default_serial_console() is wrapped into the serial_s5p driver and
the default console is picked by CONFIG_SERIAL<N> macro in config file.

serial: Implement serial_initfunc() macro

This macro simplifies declaration of weak aliases for per-driver
functions, which register these drivers with the serial subsystem.
The idea here is to push serial_register() calls from serial.c into
the drivers. To avoid pile of ifdef construct as it is now, create
weak aliases to these functions, which in case the driver is not
present alias onto an empty function, which is in turn optimized out
altogether.

disk: part_dos: don't claim whole-disk FAT filesystems

Logically, a disk that contains a raw FAT filesystem does not in fact
have a partition table. However, test_part_dos() was claiming that such
disks did in fact have a DOS-style partition table. This caused
get_device_and_partition() not to return a whole-disk disk_partition_t,
since part_type != PART_TYPE_UNKNOWN.

part_dos.c's print_partition_extended() detected the raw FAT filesystem
condition and printed a fake partition table that encompassed the whole
disk.

However, part_dos.c's get_partition_info_extended() did not return any
valid partitions in this case. This combination caused
get_device_and_partition() not to find any valid partitions, and hence
to return an error.

Fix test_part_dos() not to claim that raw FAT filesystems are DOS
partition tables. In turn, this causes get_device_and_partition() to
return a whole-disk disk_partition_t, and hence the following commands
work:

fatls mmc 0 /
fatls mmc 0:auto /

An alternative would be to modify print_partition_extended() to detect
raw FAT filesystems, just like print_partition_extended() does, and to
return a fake partition in this case. However, this seems logically
incorrect, and also duplicates code, since get_device_and_partition()
falls back to returning a whole-disk partition when there is no partition
table on the device.

FAT: check for partition 0 not 1 for whole-disk fs

The recent switch to use get_device_and_partition() from do_fat_ls()
broke the ability to access a FAT filesystem directly on a whole device;
FAT only works within a partition on a device.

This change makes e.g. "fatls mmc 0:0" work; explicitly requesting
partition ID 0 is something that get_device_and_partition() fully
supports. However, fat_register_device() expects partition ID 1 to be
used in the full-disk case; partition ID 1 was previously implicitly
specified when the user didn't actually specify a partition ID. Update
fat_register_device() to expect the correct ID.

This change does imply that if a user explicitly executes "fatls mmc 0:1"
then this will fail, and may be a change in behaviour.

Note that this still prevents "fatls mmc 0:auto" from working. The next
patch will fix that.
