Paul Mackerras 18120f153d MMU: Implement a vestigial partition table 
This implements a 1-entry partition table, so that instead of getting
the process table base address from the PRTBL SPR, the MMU now reads
the doubleword pointed to by the PTCR register plus 8 to get the
process table base address.  The partition table entry is cached.

Having the PTCR and the vestigial partition table reduces the amount
of software change required in Linux for Microwatt support.

Paul Mackerras ec5730a75a tests: Add tests for lq/stq and lqarx/stqcx. 
Lq and stq are tested in both BE and LE modes (though only 64-bit
mode) by the 'modes' test.

Lqarx and stqcx. are tested by the 'reservation' test in LE mode mode
(64-bit).
