These functions have been introduced by commit 10a8c383 (irq: introduce

patch moves them to linux/irqchip/chained_irq.h so that generic irqchip
drivers do not rely on architecture specific header files.

The Kconfig entry for SMDK2440_CPU2442 was moved from one Kconfig file
to another in commit acf2d41d ("ARM: S3C24XX: Move mach-s3c2440/
pll into mach-s3c24xx/"). In that move it also lost its statement to
select CPU_S3C2442. That was not needed anymore because it now depended
on that same symbol.

But without its select this entry became a nop: enabling it has no
effect, as it changes no code. It can safely be removed.

Fix a related, and trivial, comment typo too.

As per the Exynos5250 User Manual:
When there are pending interrupt events, WFI/WFE instruction are
ignored. To cancel the power-down sequence follow these steps:
1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register
2) Clear WAKEUP_STAT register
3) Enable interrupt service routine for CPU

Code for early wakeup for exynos already exists. Remove the panic
on suspend failure, clear the wakeup state register and return 1
from cpu_suspend to indicate a failed suspend (to a user daemon).

Older Samsung SoCs have similar panics and I have removed them all.
