patch - arm - define SYS_CACHELINE_SIZE for mx5

mx5 is a cortex-a8 which has 64 byte cache lines. i'll need this for
adding gadget support to usbarmory, but it's a property common the the
entire SoC family - may as well make it available to all MX5 boards

Works on usbarmory; compile-tested on mx53loco and mx51_efikamx too
