watchdog: sp805: fix restart handler
commit ea104a9e4d3e9ebc26fb78dac35585b142ee288b upstream.
The restart handler is missing two things, first, the registers
has to be unlocked and second there is no synchronization for the
write_relaxed() calls.
This was tested on a custom board with the NXP LS1028A SoC.
