baytrail: fix direct irq pad configuration
When a pad is configured for direct IRQ it needs to be in
non-legacy. Additionally, the signal is passed directly to
the APIC by setting the LEVEL and TPE bits in the pad config
register. The APIC can then be configured for level, edge,
and rising/falling.

BUG=chrome-os-partner:22863
BRANCH=None
TEST=Built and booted with this config. Trackpad is firing interrupts
more than it should, but it appears to be a trackpad firmware
and/or configuration issue.
