host_event_commands: Fix lpc_get_next_host_event for 64-bit events
__builtin_ffs takes an int as argument, and, therefore, does not
find bits >= 32. Fix this up when CONFIG_HOST_EVENT64.
BUG=b:69329196
BRANCH=fizz,poppy
TEST=Patch coreboot to add bit 33 in SCI mask, add EC code to send
such events, EC does not watchdog anymore
