arm: tegra: power: lp0 wake enable modified
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.
