Move application_check_valid() in bootentry.c to armcm_boot.c and make
the check specific to the ARM cortex-m. On these ARM machines it is
easier to validate the application stack address.
Also rename jump_to_application() to application_jump().
Also rename flash_read_block() to application_read_flash() and move to
armcm_boot.c .
