target/arm: Use tlb_set_page_full
Adjust GetPhysAddrResult to fill in CPUTLBEntryFull,
so that it may be passed directly to tlb_set_page_full.
The change is large, but mostly mechanical. The major
non-mechanical change is page_size -> lg_page_size.
Most of the time this is obvious, and is related to
TARGET_PAGE_BITS.
