If a board has all 8 data lines routed, the SD/MMC controller can still
operate in 4-bit (or presumably even 1-bit) mode. Adjust Tegra's MMC
driver to report the 4-bit capability even for 8-bit slots.

Add support for CONSOLE_MUX to tegra-kbc driver. This requires
adding a flag to struct keyb to know the driver has already been
initialized so if we try to initialize it again we can just return
success. Also call into iomux_doenv() from drv_keyboard_init to
re-evaluate the stdin string.

TrimSlice's USB1 port has two purposes; it either acts as a device port
hosting Tegra's USB recovery protocol, or acts as a host port connected
to the internal USB->SATA bridge chip, which may in turn be connected to
an SSD or HDD. Add the appropriate device tree and board configuration
options to enable this port as a host port, and route the port to the
SATA bridge using the VBUS GPIO.

When the cursor position gets to the end of the LCD console we normally
scroll by one line. This adds an option to increase that value.
Console scrolling is often slow, and if a large amount of output is
being sent, increasing this option to 10 or so will speed things up
considerably.

The normal alignment is PAGE_SIZE, but if this is defined, we can support
other alignments.
The motivation for this change is to make the display section-aligned on
ARM so that we can easily turn off data caching for the frame buffer region
without resorting to level 2 page tables.

Add support for adjusting the L1 cache behavior by updating the MMU
configuration. The mmu_set_region_dcache_behaviour() function allows
drivers to make these changes after the MMU is set up.
It is implemented only for ARMv7 at present.
This is needed for LCD support, where we want to make the LCD frame buffer
write-through (or off) rather than write-back.

Add LCD definitions and also a proposed binding for LCD displays.
The PWM is as per what will likely be committed to linux-next soon.
The displaymode binding comes from a proposal here:
http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html
The panel binding is new, and fills a need to specify the panel
timings and other tegra-specific information. Should a binding appear
that allows the pwm to handle this automatically, we can revisit
this.
