xlat: Fix compatibility between v1 and v2

Browse Source 
There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.

This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.

The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.

This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).
