The following patch changed the PFUZE100 swbst register bit definitions
and broke PMIC configuration on multiple boards, at least on the novena
and gw_ventana. This patch fixes it.

To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg
to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper.
The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg
when ddr_type is for DDR3. Later we can use ddr_type to initialize
MMDC for LPDDR2.
Initialize ddr_type for different boards which enable SPL.

The fdt_file1 and fdt_file2 vars provide fallbacks for the fdt file loading
script. There is no need to allow the user to override these as if they
want to specify the fdt, they should do so in the first attempt which is
the fdt_file var.

Move shared functions used by both SPL and U-Boot to common.c:
- setup_iomux_uart() and uart pad config
- gpio pad config
In the process also moved the following to common.c in preparation for
calling it from the SPL:
- split i2c setup into a shared function
- move pmic init to setup_pmic() function to call directly from
power_init_board()
- split gpio setup into early (iomux and default pin config)
and late (output configuration based on env)

The clock gating must be setup prior to calling arch_cpu_init(). Without this
booting to SD (directly via eFuse or via bmode) will hang.

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.

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.
