GPIO based lp0 wakeup needed to support search for its irq
as well as GPIO bank irq in table. This is implemented
in this change.
lp0 wakeup irq enable using enable_irq_wake needs to be
called in specific drivers. Additionally, in some cases
wake irq needs to be updated in tegra wakeup table.

Adding api to configure pins in gpio mode with init value before
gpio library is up. This will provide to configure the pins in
initial state and avoid any glitch in pins.

Adding the support in function gpio_to_irq() such that the external
gpio peripheral driver can provide the gpio to irq number through
their gpio implementation.

The default value of ARCH_NR_GPIOS is defined to 256. That is not enough
for Tegra based board such as ventana. Ventana has 224 gpios on Tegra
soc and other gpio expanders like PMU and audio codecs. Extended GPIO
numbers to make external gpio pins work.

To give one place to setup the pins that are used as GPIOs instead
of as their pinmuxed functions. Specifying enabled as false explicitly
disables the gpio mode of that pin (if left on by firmware).
This should remove the need for calling these from specific drivers and
thus reduce tegra-specific code from them.
