Mulin Chao 3391ef950a npcx: shi: Improve reliability of SPI host command interface ...

- Fix output buffer filling races
- Limit response size to 256 bytes to work-around forced low bit on
  257th byte
- Modify CS glitch to handle CS-to-clock delay
- Make CS GPIO interrupt pri 0 to ensure SHI interrupts aren't serviced
  first

TEST=`while true; do ectool version; done > /usr/local/log` on kevin,
verify failure occurs about every ~72000 commands (~360000 host commands)
BRANCH=None
