GPIO lookup tables are supposed to be zero terminated. Let's do that
and avoid accidentally walking off the end.

On some BYT PLatform the PWM is controlled using CRC PMIC. Add a lookup
entry for the same to be used by the consumer (Intel GFX)

On some Intel SoC platforms, the panel enable/disable signals are
controlled by CRC PMIC. Add those control as a new GPIO in a lookup
table for gpio-crystalcove chip during CRC driver load

Surely GPIO irq will be used as an input pin so make sure its direction is

intel_soc_pmic_find_gpio_irq() tries to find a GPIO interrupt but doesn't
select between it or I2C interrupt so it makes more sense to move this
comment to intel_soc_pmic_i2c_probe() with minor edits.
