feat(zynqmp): add hooks for mmap and early setup
Add early setup hooks (via custom_early_setup()) and provide a way
to cover custom memory mapping which includes extending memory map
via custom_mmap_add().
This likely also require to align MAX_XLAT_TABLE, MAX_XLAT_TABLES
macros. It can be done for example by defining these macros in
custom_pkg.mk
MAX_MMAP_REGIONS := XY
$(eval $(call add_define,MAX_MMAP_REGIONS))
MAX_XLAT_TABLES := XZ
$(eval $(call add_define,MAX_XLAT_TABLES))
custom_early_setup() can be used for early low level operations
related to setting up the system to correct state.
