x86: ahci: Make sure interface is not busy after enabling the port

Each time U-Boot boots on Intel Crown Bay board, the displayed hard
drive information is wrong. It could be either wrong capacity or just
a 'Capacity: not available' message. After enabling the debug switch,
we can see the scsi inquiry command did not execute successfully.
However, doing a 'scsi scan' in the U-Boot shell does not expose
this issue.

SCSI:  Target spinup took 0 ms.
SATA link 1 timeout.
AHCI 0001.0100 32 slots 2 ports 3 Gbps 0x3 impl SATA mode

So uninitialized contents on the stack were passed to dev_print() to
display those wrong information.

The symptom were observed on two hard drives (one is Seagate, the
other one is Western Digital). The fix is to make sure the AHCI
interface is not busy by checking the error and status information
from task file register after enabling the port in ahci_port_start()
before proceeding other operations like scsi_scan().

ARM: UniPhier: remove __packed that causes a problem on GCC 4.9

The DDR PHY training function, ddrphy_prepare_training() would not
work if compiled with GCC 4.9.

The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h)
is specified with __packed because it represents a hardware register
mapping, but it turned out to cause a problem on GCC 4.9.

If -mno-unaligned-access is specified (yes, it is in
arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the
__attribute__((packed)) and generates extra instructions to perform
the memory access in a way that does not cause unaligned access.
(Actually it is not need here because the register base, the first
argument of the ddrphy_prepare_training(), is always given with a
4-byte aligned address.)

Anyway, as a result, readl() / writel() is divided into byte-wise
accesses.  The problem is that this hardware only accepts 4-byte
register access.  Byte-wise accesses lead to unexpected behavior.

There are some options to avoid this problem.

[1] Remove -mno-unaligned-access
[2] Add __aligned(4) along with __packed to struct ddrphy
[3] Remove __packed from struct ddrphy

[1] solves the problem for ARMv7, but it does not for pre-ARMv6 and
ARMv6-M architectures where -mno-unaligned-access is default.
So, [1] does not seem reasonable in terms of code portability.

Both [2] and [3] work well, but [2] seems too much.  All the members
of struct ddrphy have the u32 type.  No padding would be inserted
even if __packed is dropped.

sunxi: display: Make lcd display clk phase configurable

While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module
I noticed that the screen flickered. This is caused by the lcd display clk
phase reg value being set to 0, where it should be 1 in this setup.

This commit adds a Kconfig option for the lcd display clk phase, so that we
can set it per board. This defaults to 1, because looking at all the fex
files in sunxi-boards, that is by far the most used value.

This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the
default of 1 with 0, as that is the correct value for those tablets, this
keeps the register settings the same as before this commit.

The Olinuxino-A13 defconfigs are not updated, changing the register setting
for these boards from 0 to 1, this is intentional.

sunxi: Restore lowlevel_init usage

2 recent sunxi changes have removed the usage of lowlevel_init by moving some
code around and then setting CONFIG_SKIP_LOWLEVEL_INIT.
This is problematic for 2 reasons:

1) It does not just stop s_init from being called, it also stops
cpu_init_cp15 from getting called, which is undesirable.

2) We want u-boot.bin to be usable standalone, without SPL, some people e.g.
use an upstream u-boot.bin together with Allwinner's boot0 loader. So
u-boot.bin must (re)initialize the gpios, timer, etc.

This commit restores the lowlevel_init / s_init usage, while keeping the
changes to no longer use the global-data (gd) struct in the SPL.
