flash/nor/niietcm4: minor fixes 

niietcm4_write() buffer padding:
add correct buffer padding for 16 bytes.

Args check in FLASH_BANK_COMMAND_HANDLER():
first version of the driver had 7 args, current - 6. This patch will fix
error when flash is rejected (current k1921vk01t.cfg has flash bank init
with 6 args).

Timeouts in flash flag checking procedure:
increase timeouts in niietcm4_opstatus_check() and niietcm4_uopstatus_check()
cause there were problems in some hardware configurations.

JTAG ID:
wrong id in k1921vk01t.cfg replaced with right one.
