mb/google/zork: Set vw_irq_polarity from low to high

The EC used on zork uses a level high interrupt. This change configures
the polarity correctly.

The eSPI config is baked into RO verstage. The zork ToT build doesn't
use signed verstage since it's incompatible with the ToT version of
vboot. This means we can safely switch the keyboard IRQ polarity.

NOTE: Do not cherry pick this into the Zork firmware branch!

BUG=b:160595155
TEST=On morphius verify keyboard works as correctly and no spurious
interrupts are thrown on S0i3 resume. Also verified keyboard and mouse
work correctly in windows.
