This fixes test failures caused by the new linker warning which report:
./ld/ld-new: warning: load.S.x has a LOAD segment with RWX permissions
Fix this by splitting the linker MEMORY into ram and rom to avoid
generating RWX sections. This required tests to be adjusted to fix
issues with the move. Namely:
- fpu tests: were incorrectly using l.ori with ha(anchor) which now
that we pushed the anchor up in memory it exposes the bug. Update
to used the correct l.movhi instruction instead.
- adrp test: the test reports ram offset addresses, now that we have
moved memory layout around a bit I adjusted the test output. Some
padding is added before pi to show that the actual address of pi and
the adrp page offset are not the same.
