Without usb-serial cable plugged at this stage, some
garbage is seen in UART RX FIFO, which blocks autoboot
progress. The fix makes sure to empty the RX FIFO,
before we wait for user input to interrupt autoboot.

Configuration in vexpress and u8500.v1 is different from what
is needed in u8500.v2. As such, card configuration specifics need
to reside in the board file rather than the driver.

This renames BOARD_LATE_INIT to CONFIG_BOARD_LATE_INIT.
Along the way it removes some leftover
#define BOARD_LATE_INIT 1
and adds some basic documentation for board specific
callbacks in README.

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.
MAKEALL didn't report any errors related to this that I could see.
