!boards: Remove NSH_ARCHINIT and board_app_initialize

Browse source 
BREAKING: In an effort to simplify NuttX initialization, NSH_ARCHINIT is
removed. board_app_initialize is also removed. BOARD_LATE_INITIALIZE now
performs all board initialization logic, and is by default enabled. All
references to these symbols are removed. BOARDIOC_INIT remains, but will
result in -ENOTTY when called. It is to be removed in a later commit.

Quick fix: Boards relying on NSH_ARCHINIT should now enable
CONFIG_BOARD_LATE_INITIALIZE instead. If the application needs
fine-grained control over board initialization from userspace, the logic
performed by BOARDIOC_INIT may be copied to the board_finalinitialize
function and used instead via BOARDIOC_FINALINIT. All
board_app_initialize logic provided by NuttX is now moved to
board_late_initialize, and the same should be done for out-of-tree
boards.
