Jason Liu 9779f0e1d7 ARM: imx: i.mx6d/q: disable the double linefill feature of PL310 
The L2 cache controller(PL310) version on the i.MX6D/Q is r3p1-50rel0
The L2 cache controller(PL310) version on the i.MX6DL/SOLO/SL is r3p2
But according to ARM PL310 errata: 752271
ID: 752271: Double linefill feature can cause data corruption
Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2
Workaround: The only workaround to this erratum is to disable the
double linefill feature. This is the default behavior.

without this patch, you will meet the following error when run the
memtester application at: http://pyropus.ca/software/memtester/
