Alternative physmap via memory:physical@<mem type>.

Jacob Lorentzon requested to merge 4lDO2/kernel:replace_physmap into master

Allows doing what SYS_PHYSMAP does but using SYS_FMAP (allows setting PROT_WRITE, same as PHYSMAP_WRITE), and where PHYSMAP_NO_CACHE and PHYSMAP_WRITE_COMBINE are replaced by 3 separate "files", i.e. memory:physical@wb/memory:physical, memory:physical@uc, and memory:physical@wc.
