Modify tegra-common-post.h's BOOTCOMMAND definition to use the generic
filesystem command load rather than separate fatload and ext2load.
This removes the need to iterate over supported filesystem types in the
boot command.
This requires editing all board config headers to enable the new
commands. The now-unused commands are left enabled to assue backwards
compatibility with any user scripts. Boards (all from Avionic Design)
which define custom BOOTCOMMAND values are not affected.

Harmony contains an SD slot with all 8 bits routed. This allows plugging
in an eMMC-chip-in-SD-form-factor.
Seaboard/Springbank/Ventana/AC100 all have an eMMC chip with all 8 bits
hooked up.
Now that the U-Boot eMMC code fully supports 8-bit operation, initialize
those ports as 8-bit instead of 4-bit to improve performance.
Whistler was already registering its ports as 8-bit.
TrimSlice doesn't have any 8-bit ports.

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.

The displaymode binding comes from a proposal here:
