vexpress64: Add BASER_FVP vexpress board variant
The BASER_FVP board variant is implemented on top of the BASE_FVP board
config (which, in turn, is based on the Juno Versatile Express board
config). They all share a similar memory map - for BASER_FVP the map is
inverted from the BASE_FVP
(https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map)
* Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same
board config as BASE_FVP and JUNO
* Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename
to vexpress_aemv8.h)
* Enable config to switch to EL1 for the BASER_FVP
* Create vexpress_aemv8r defconfig
* Provide an MPU memory map for the BASER_FVP
For now, only single core boot is supported.
