xlat_tables_v2: fix assembler warning of PLAT_RO_XLAT_TABLES
If PLAT_RO_XLAT_TABLES is defined, the base xlat table goes to the
.rodata section instead of .bss section.
This causes a warning like:
/tmp/ccswitLr.s: Assembler messages:
/tmp/ccswitLr.s:297: Warning: setting incorrect section attributes for .rodata
It is practically no problem, but I want to keep the build log clean.
Put the base table into the "base_xlat_table" section to suppress the
assembler warnings.
The linker script determines its final destination; rodata section if
PLAT_RO_XLAT_TABLES=1, or bss section otherwise. So, the result is the
same.
