nb/intel/x4x/raminit: Change reset type on incomplete raminit reset
The checkreset() function checks if raminit previously
succeeded (pmcon2 bit7 == 0). If this is not the case it will issue a
hot reset (writing 0x6 to 0xcf9). On the next attempt to boot the
system BOOT_PATH_RESET path will be taken. This boot path can only
successfully initialize memory if the system was reset from a state
where raminit succeeded, which is not the case here.
This can be fixed by issuing a cold reset instead of a hot reset.
