ARM: vmlinux-xip.lds.S: fix multiple issues
The XIP linker script has several problems:
- PAGE_ALIGNED_DATA is missing and is likely to end up somewhere with
the wrong LMA.
- BUG_TABLE definitely has the wrong LMA, it is not copied to RAM, and
its VMA is unaccounted for and likely to clash with dynamic memory
usage.
- TCM usage is similarly broken.
- PERCPU_SECTION is left in ROM despite being written to.
Let's use generic macros for those things and locate them appropriately.
Incidentally, those macros are usable with a LMA != VMA already by
properly defining LOAD_OFFSET.
TCM is not fixed here. It never worked in a XIP configuration anyway, so
that can wait until another round of cleanups.
