[PATCH xserver] Add definitions for the AArch64 architecture

[Thomas Petazzoni]

AArch64 is the new 64 bits architecture from ARM, for which a few
definitions are needed in the X.org server to make it build properly.

Like for the ARM 32 bits architecture, we for now assume that AArch64
will be used in Little Endian mode for Linux.
