Subject: [PATCH v2 5/5] arm64: dts: qcom: add wake up interrupts for GPIOs for SDM845

GPIOs that are wakeup capable have interrupt lines that are routed to
the always-on interrupt controller (PDC) in parallel to the pinctrl. The
interrupts listed here are the wake up lines corresponding to GPIOs.

Signed-off-by: Lina Iyer <ilina@...eaurora.org>

Changes in v1:
	- Use interrupt-extended for all TLMM interrupts
	- Define GPIO-PDC map using interrupt-names
