The PDC irqchip driver currently does not handle dual-edge interrupts,
and we have google,lazor board with sc7180 designed to configure gpio28
as a dual-edge interrupt. This interrupt is however not expected to be
wakeup capable on this board, so an easy way to fix this, seems to be to
make this gpio non wakeup capable and let TLMM handle it (which is capable
of handling dual-edge irqs)
To be able to do so only on this board, so other boards designed with
this SoC can continue to use gpio28 as a wakeup capable one, make a
copy of msm_gpio_wakeirq_map for lazor and remove gpio28 from the
list.
