msm: gpio-v2: Fix spurious interrupts when gpio-irq is unmasked

To unmask a gpio interrupt, the gpio driver sets the
INTR_RAW_STATUS_EN and INTR_ENABLE bits in the INTR_CFG register.
As soon as the INTR_RAW_STATUS_EN is set, the INTR_STATUS is updated
and this causes a spurious interrupt when the irq is enabled.
This is noticed frequently when the gpio is pulled high and requests
a rising edge interrupt or pulled low and is requesting a falling edge
interrupt.
Due the internal circuit design of the TLMM IRQ block, the above method
causes a spurious interrupt when the irq was initialized.
Hence, to avoid this behavior we set the INTR_RAW_STATUS_EN, clear the
INTR_STATUS only once during setup. Every mask and unmask only toggles
the INTR_ENABLE bit.

arm: free all .init memory when CONFIG_STRICT_MEMORY_RWX is set

When CONFIG_STRICT_MEMORY_RWX is set, the .init section is
padded to the next megabyte boundary. The part of the .init
section past __init_end (i.e. the pad) was not being freed
since the kernel uses the address of __init_end to determine
how much memory to free.

The fix is to set __init_end to the end of the pad.
