mach-exynos: UNIVERSAL5410 MMC: Enable SDR104, double bus bandwidth

Enable SDR104 UHS SD card modes and double the controller's bus bandwidth to 160MHz.

Tested on various SD cards and max read jumps from ~35mB/s to +70mB/s.
staging: zram: add per-cpu support to Crypto

Since original zram code did not implement any per-cpu operations,
my previous patch (staging: zram: add Crypto API support) did not
include them either.

This patch complements the first one with per-cpu support for Crypto,
allocating tfms buffer separately for each online processor.
Changes are based on zswap and zcache per-cpu code.

Basic tests (concurrent writing several 10-40MB chunks to zram) performed
on an ARM-based EXYNOS4412 Quad-Core showed that per-cpu code provides
noticeable time saving, ranging between 30-40% for LZO and LZ4 compressors.
Sample data (LZO): writing 160MB, 40MB per thread took 0.60s with per-cpu
code included and approximately 0.80s without per-cpu support.
