Some device has large pages that take up to 2s to erase. Add support to send a deferred erase command, that willi be processed on HOOK task. It can leave the other tasks (HOST_CMD) responsive. If the whole EC can stall on flash erase, like the STM32F4 do, at least the command FLASH_ERASE_GET_RESULT can be retried when it times out. BRANCH=none TEST=Check with flashrom doing a loop of overwrites.
