Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,input-wakeup" boolean property to enable the
wakeup source, "wakeup-source" is the new standard binding.

This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

The s5p-sss crypto HW acceleration driver supports only AES algorithms
thus it accesses only registers from feeder (offset 0x0, length 0x100)
and AES (offset 0x200, length 0x100) blocks of Security SubSystem (SSS).

The exynos-rng Pseudo Random Number Generator driver accesses only PRNG
block at offset 0x400 (length 0x100).

Narrow the size of memory mapped by s5p-sss driver so both drivers can
be loaded at the same time.

add masks for the Cache and Op field within the cache op.
