MLK-10496: Check the PL310 version for applying erratakk4.4.3_2.0.1imx_v2014.04_kk4.4.3_2.y
Apply errata based on PL310 version instead of compile
time. Also set Prefetch offset to 15, since it improves
memcpy performance by 35%. Don't enable Incr double
Linefill enable since it adversely affects memcpy
performance by about 32MB/s and reads by 90MB/s. Tested
with 4K to 16MB sized src and dst aligned buffer.
