PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.
By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

Rename all i.MX6 pad declarations to MX6_PAD_x, so a board
may support either i.MX6Quad/Dual (MX6Q) or i.MX6Dual-Lite/Solo
(MX6DL) by including the proper header.
Boards mx6qarm2, mx6qsabreauto, mx6qsabrelite, and mx6qsabresd
only support MX6Q, so they include mx6q_pins.h.

On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not
suitable for the multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).
This patch fixes this issue by adding a configuration field for the SDHC input
clock frequency.

The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so
disable it globally for this architecture. This avoids setting no_snoop for all
i.MX boards, and it prevents setting a reserved bit of a reserved register if
fsl_esdhc_mmc_init() is used on i.MX, like in
arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().
Since no_snoop was only used on i.MX, get rid of it BTW.

Commit 314284b156 has
changed board_mmc_getcd() function prototype, while
mx6qarm2 has still the old one.

This enable the network function on the i.mx6q armadillo2
board(arm2), thus we can use tftp to load image from network.

Add the initial support for Freescale i.MX6Q Armadillo2 board
Support: MMC boot from slot 0/1, debug UART(UART4), usdhc.
There is two MMC slots on the boards:
mmc dev 0 -> connect USDHC3 -> the lower slot on the board,
mmc dev 1 -> connect USDHC4 -> the upper slot on the board,
