vboot: push clear recovery mode switch until BS_WRITE_TABLES

Browse Source 
Serves two purposes:

(1) On some platforms, FSP initialization may cause a reboot.
Push clearing the recovery mode switch until after FSP code runs,
so that a manual recovery request (three-finger salute) will
function correctly under this condition.

(2) The recovery mode switch value is needed at BS_WRITE_TABLES
for adding an event to elog.  (Previously this was done by
stashing the value in CBMEM_ID_EC_HOSTEVENT.)
