The CrystalCove GPIO irqchip doesn't have irq_set_wake callback defined
so we should set IRQCHIP_SKIP_SET_WAKE for it or it would cause an irq
desc's wake_depth unbalanced warning during system resume phase from the
gpio_keys driver, which is the driver for the power button of the ASUS
T100 laptop.Signed-off-by: Aaron Lu

The CrystalCove GPIO chip has can_sleep set so its demultiplexed irqs
will have IRQ_NESTED_THREAD flag set, thus we should use the nested
version handle_nested_irq in CrystalCove's irq handler instead of
handle_generic_irq, or the following warning will be hit and the
functionality is lost:[ 4089.639554] Hardware name: ASUSTeK COMPUTER INC. T100TA/T100TA, BIOS T100TA.313 08/13/2014

The virtual GPIO introduced in ACPI table of Baytrail-T based system is
used to solve a problem under Windows. We do not have such problems
under Linux so we do not actually need them. But we have to tell GPIO
library that the Crystal Cove GPIO chip has this many GPIO pins or the
common GPIO handler will refuse any access to those high number GPIO
pins, which will resulted in a failure evaluation of every ACPI control
method that is used to turn on/off power resource and/or report sensor
temperatures.Signed-off-by: Aaron Lu

Devices based on Intel SoC products such as Baytrail have a Power
Management IC. In the PMIC there are subsystems for voltage regulation,
A/D conversion, GPIO and PWMs. The PMIC in Baytrail-T platform is
called Crystal Cove.This patch adds support for the GPIO function in Crystal Cove.
