fix(xlat): remove always true check in assert

This issue was found with Clang compiler:
lib/xlat_tables_v2/aarch32/xlat_tables_arch.c:206:34:
 error: result of comparison of constant 4294967296 with expression
 of type 'uintptr_t' (aka 'unsigned long') is always true
 [-Werror,-Wtautological-constant-out-of-range-compare]
                assert(virtual_addr_space_size <=
                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~

On AARCH32, MAX_VIRT_ADDR_SPACE_SIZE is defined as 1 << 32, and a 32 bit
uintptr_t is always lower.
Just remove the assert line.
