linker_script: replace common read-only data with RODATA_COMMON
The common section data are repeated in many linker scripts (often
twice in each script to support SEPARATE_CODE_AND_RODATA). When you
add a new read-only data section, you end up with touching lots of
places.
After this commit, you will only need to touch bl_common.ld.h when
you add a new section to RODATA_COMMON.
Replace a series of RO section with RODATA_COMMON, which contains
6 sections, some of which did not exist before.
This is not a big deal because unneeded data should not be compiled
in the first place. I believe this should be controlled by BL*_SOURCES
in Makefiles, not by linker scripts.
When I was working on this commit, the BL1 image size increased
due to the fconf_populator. Commit c452ba159c14 ("fconf: exclude
fconf_dyn_cfg_getter.c from BL1_SOURCES") fixed this issue.
I investigated BL1, BL2, BL2U, BL31 for plat=fvp, and BL2-AT-EL3,
BL31, BL31 for plat=uniphier. I did not see any more unexpected
code addition.
