The LM006 USB WiFi adapter uses a Realtek RTL8188CUS chipset,
which requires the compatible firmware RTL8192CU.

With the cfgblock command in U-Boot we now have a better solution.

Don't write the eMMC twice on Apalis in the not migrate case.

Since we use USB Gadget ConfigFS now use libusbg to load the
USB Gadget configuration automatically.

Up until now, U-Boot for Colibri VF50/VF61 did not had an
environment variable board_name. Use the soc environment
variable to set the board_name.

To avoid code duplication call fwd_blk from fwd_mmc. This adds
one more indirection, but since flash_mmc.img is a compatibility
script anyway it is not the common case...

Source the update script only if loading succeeded. This avoids
loops if board_name is not set. Also add a test if board_name is
really set since this variable is/was not available in older
U-Boots.

Further generalise U-Boot update scripts by using ${board_name} instead
of hard coding module name like apalis_t30, colibri_t20 or colibri_t30.

Even though our downstream L4T based kernel does not use any
device tree stuff prepare for easy deployment thereof by using the
correct dtb name.

In the Ethernet aka TFTP update case this actually fixes an issue where
it previously tried to TFTP the whole ${board_name} directory which at
least on my setup failed with a permission denied which it retried
forever.
