mb/google/guybrush: Fix EC SCI configuration

This change fixes two problems:
1) We had the enum values for .direction and .level swapped. The naming
is very confusing...
2) ESPI_SYS is not a good event to use for EC SCI. It is a level/low
event that is only cleared by reading the eSPI status register 0x9C.
Cezanne has added a new event source that directly exposes the SCI bit.
This is the correct event source to use for EC SCI.

BUG=b:186045622, b:181139095
TEST=`lpc sci` on EC console and see /proc/interrupts increase by 1
