PM520: add missing enable_interrupts()
The code disabled interrupts in several locations, without re-enabling them again. Fix this. While we are at it, also fix a GCC 4.6 build warning: flash.c: In function 'flash_erase': flash.c:373:21: warning: variable 'last' set but not used [-Wunused-but-set-variable] Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Josef Wagner <Wagner@Microsys.de>
