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
