tegra: add enterrcm command
Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.
This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

The mmc0_tftpboot option reads a kernel using TFTP but then boots from
eMMC. This allows kernel development without resorting to NFS root (which
changes some parts of the boot process).

LCD final init is now kept in board_late_init(), so we need to enable
this feature in the config.

We don't need the default serial clock now, since we try with both
options.

This was added to the non-legacy kernel boot command line in
<http://gerrit.chromium.org/gerrit/8373>. Since legacy has its own
command line, we need it too.

It is arduous to maintain two very similar config files for Tegra 2 and
Tegra3. This commit creates a new tegra-common.h to hold these common
items.
