Documentation: arm64: Update memory.rst for TBI
Most of memory.rst was written very early, at a time where TBI (Top
Byte Ignore) was not enabled. Nowadays TBI0 is always enabled, and
TBI1 may be enabled, depending on the kernel configuration. This
means that VA bits 63:56 cannot generally be assumed to have any
particular value.
Regardless of TBI, TTBRx selection is done based on bit 55; update
memory.rst accordingly.
