[v2,17/20] hw/i386/ich9: Remove redundant GSI_NUM_PINS

Commit Message

Bernhard Beschow Jan. 31, 2023, 11:53 a.m. UTC

Most code uses IOAPIC_NUM_PINS. The only place where GSI_NUM_PINS defines
the size of an array is ICH9LPCState::gsi which needs to match
IOAPIC_NUM_PINS. Remove GSI_NUM_PINS for consistency.
