ARM: 8164/1: mm: clear SCTLR.HA instead of setting it for LPAE
SCTLR.HA (hardware access flag) is deprecated and not actually implemented by any CPUs. Furthermore, it can confuse cr_alignment checks where the whole value of SCTLR is compared against the value sitting in the hardware, since the bit is actually RAZ/WI and will not match the saved cr_alignment value.
