exynos: i2c: Change FDT bus setup code to enumerate ports correctly

At present the i2c ports are enumerated in a strange way - the
fdtdec_find_aliases_for_id() function is used, but then the ID returned
is ignored and the ports are renumbered. The effect is the same provided
that the device tree has the ports in the same order, or uses aliases,
and has no gaps, but it is not correct.

Adjust the code to use the function as intended. This will allows device
tree aliases to change the device order if required.

As a result, the i2c_busses variable is dropped. We can't be sure that
there are no 'holes' in the list of buses, so must check the whole
array.

Note: it seems that non-FDT operation is now broken in this drive and
will need to be reinstated for upstream.

mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEAN

Linux modified the MTD driver interface in commit edbc4540 (with the
same name as this commit). The effect is that calls to mtd_read will
not return -EUCLEAN if the number of ECC-corrected bit errors is below
a certain threshold, which defaults to the strength of the ECC. This
allows -EUCLEAN to stop indicating "some bits were corrected" and begin
indicating "a large number of bits were corrected, the data held in
this region of flash may be lost soon". UBI makes use of this and when
-EUCLEAN is returned from mtd_read it will move data to another block
of flash. Without adopting this interface change UBI on U-boot attempts
to move data between blocks every time a single bit is corrected using
the ECC, which is a very common occurance on some devices.

For some devices where bit errors are common enough, UBI can get stuck
constantly moving data around because each block it attempts to use has
a single bit error. This condition is hit when wear_leveling_worker
attempts to move data from one PEB to another in response to an
-EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is
called to perform the data copy, and after the data is written it is
read back to check its validity. If that read returns UBI_IO_BITFLIPS
(in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to
wear_leveling worker, which then proceeds to schedule the destination
PEB for erasure. This leads to erase_worker running on the PEB, and
following a successful erase wear_leveling_worker is called which
begins this whole cycle all over again. The end result is that (without
UBI debug output enabled) the boot appears to simply hang whilst in
reality U-boot busily works away at destroying a block of the NAND

spi: exynos: Minimise access to SPI FIFO level

Accessing SPI registers is slow, but access to the FIFO level register
in particular seems to be extraordinarily expensive (I measure up to
600ns). Perhaps it is required to synchronise with the SPI byte output
logic which might run at 1/8th of the 40MHz SPI speed (just a guess).

Reduce access to this register by filling up and emptying FIFOs
more completely, rather than just one word each time around the inner
loop.

Since the rxfifo value will now likely be much greater that what we read
before we fill the txfifo, we only fill the txfifo halfway. This is
because if the txfifo is empty, but the rxfifo has data in it, then writing
too much data to the txfifo may overflow the rxfifo as data arrives.

This speeds up SPI flash reading from about 1MB/s to about 2MB/s on snow.

Fix number base handling of "load" command

As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)

This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load".  In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.

Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble.  Stephen Warren comments (see
[1]):

        I suppose you can change the behaviour if you want; anyone
        writing "0x..." for their values presumably won't be
        affected, and if people really do assume all values in U-Boot
        are in hex, presumably nobody currently relies upon using
        non-prefixed values with the generic load command, since it
        doesn't work like that right now.
