----------------------------------------------------------------
Tidy up open coded relative references in asm

Use the newly introduced adr_l/ldr_l/str_l/mov_l assembler macros to
replace open coded VA-to-PA arithmetic in various places in the code. This
avoids the use of literals on v7+ CPUs, reduces the footprint of the code
in most cases, and generally makes the code easier to follow.
