Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".

Most of the drivers available for Vybrid are not yet converted
to OF model to use device tree model, only few drivers
like SPI and GPIO drivers use device trees.
Add separate defconfig for who needs to use device tree model.
Later this can be integrated to single defconfig.

Like SPI and I2C few GPIO controllers also have
multiple chip instances. This patch adds the
flag 'DM_UC_FLAG_SEQ_ALIAS' in gpio_uclass driver
to control device sequence numbering. By defalut
the dev->r_seq for gpio_uclass will alwalys
returns -1, which leads the gpio driver probe
failure when using the driver with device trees.

Commit 81830581 ("imx6: centralise common boot options in
mx6_common.h") broke boot on mx6sl and mx6sx by assuming that all mx6
SoCs use the same LOADADDR/SYS_TEXT_BASE range, which is not correct.

DDR on mx6sx/mx6sl starts at 0x80000000.

Adjust LOADADDR/SYS_TEXT_BASE to the proper values for mx6sx/mx6sl,
so that these SoCs can boot again.

Also, TQMA6 requires a custom CONFIG_SYS_TEXT_BASE value, so move
its setting prior to the inclusion of mx6_common.h.

The fdt_file1 and fdt_file2 vars provide fallbacks for the fdt file loading
