This commit combines catching missing memory and calibration data into
one if() block. It further prints pertinent information in determining
why the failure occurred.

The initial revision of the GW551x does not connect enough signals between
the HDMI receiver and the IMX6 CSI for 16bit capture mode necessary for
yuv422smp capture. Future revisions will, but for the initial rev force it
to yuv422bt656 mode which requires an 8bit video data bus.

The HDMI receiver used on the GW54xx and GW551x has a 16bit video data bus
interconnect between it and the IMX6 CSI. This can be used in two different
modes, each having advantages and disadvantages. Allow the hdmiinfmt env
var to specify which format is desired (yuv422smp or yuv422bt656).

This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).
Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
gsc wd enable [30|60]
gsc wd disable
Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.

The GW551x-A revision does not have the CSI0_DATA_EN pin connected, therefore
we need to make sure that signal is not muxed to the CSI_DATA_EN signal
internally and do so by steering it to the unused GPIO5_IO20.
We do this so that the kernel device-tree can properly define the signal for
RevB and beyond boards that do have this hooked up properly and require it.

A board level errata causes the IMX6 watchdog to be unstable on the GW51xx
RevA and RevB boards which can cause the watchdog to trip extremely early
(under 5seconds) under certain operating conditions. Disable the watchdog
node in the device-tree to work around this issue.

The IMX6 Datasheets specifies that when the IMX6 LDO is enabled
(internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to
provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive)
and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV
shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.

Since commit 32df39c741788e ("mx5: fix get_reset_cause") we have the following
boot messages on a mx53qsb:
U-Boot 2015.04-rc5-00029-gd68df02 (Apr 06 2015 - 11:15:39)
CPU: Freescale i.MX53 rev2.1 at 800 MHz
Reset cause: POR
Board: MX53 LOCO
I2C: ready
DRAM: 1 GiB
MMC: FSL_SDHC: 0, FSL_SDHC: 1
In: serial
Out: serial
Err: serial
CPU: Freescale i.MX53 rev2.1 at 1000 MHz
Reset cause: unknown reset
Net: FEC [PRIME]
The CPU and Reset cause lines appear twice.
Initially mx53 boots at 800MHz, then at a later point the PMIC is configured via
I2C to raise the CPU voltage so that it can run at 1GHz.
To avoid such misleading double printings, disable printing cpu info for now.

There're 2 versions of motherboards that could be used in ARC SDP.
The only important difference for U-Boot is different NAND IC in use:
[1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP
while
[2] v3 board sports MT29F4G16ABADAWP
They are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing
board type we're running on.
