target/mips: Revert TARGET_PAGE_BITS_VARY
Revert ee3863b9d41 and a08d60bc6c2b.  The logic behind changing
the system page size because of what the Loongson kernel "prefers"
is flawed.

In the Loongson-2E manual, section 5.5, it is clear that the cpu
supports a 4k page size (along with many others).  Similarly for
the Loongson-3 series CPUs, the 4k page size is mentioned in the
section 7.7 (PageMask Register).  Therefore we must continue to
support a 4k page size.
