[PATCH 3/5] ARM: mm: cache-l2x0: Use l2c_write_sec() for LATENCY_CTRL registers

[Tomasz Figa]

According to the documentation, TAG_LATENCY_CTRL and DATA_LATENCY_CTRL
registers of L2C-310 can be written only in secure mode, so
l2c_write_sec() should be used to change them, instead of plain
writel_relaxed().
