msm: memutils: memcpy, memmove optimization

1. To fit 8x26 64-bytes cache line size, we change preload steps as 64Bytes.
2. According to tune result, change preload distance as 5 cache lines.
3. According to tune result, re-arrange the ld/str order as back-to-back
   for copy_from_user.

The markable improvement:
	memcpy : 5%
	copy_to_user : 9%
	copy_from_user : 13%
	memmove : 37%

cpufreq_intellimm: intelliminmax cpu governor initial baseline commit

intelliminmax (intellimm) governor is designed to work with the newer SOCs with fixed voltage rails (ie MSM8974+ SOCs).  It is designed to work within those
fixed voltage ranges in order to maximize battery performance while creating a
smooth UI operations.
