mb/google/octopus: Add EC_HOST_EVENT_PANIC to SCI mask

Adding EC_HOST_EVENT_PANIC to SCI mask allows the EC to interrupt the
Kernel when an EC panic occurs. If system safe mode is also enabled
on the EC, the kernel will have a short period to extract and save info
about the EC panic.

BUG=b:268342532
BRANCH=firmware-octopus-11297.B
TEST=Observe kernel ec panic handler run when ec panics
