target/mips: Add CP0 PWCtl register
Add PWCtl register (CP0 Register 5, Select 6).
The PWCtl register configures hardware page table walking for TLB
refills.
This register is required for the hardware page walker feature. It
exists only if Config3 PW bit is set to 1. It contains following
fields:
PWEn (31) - Hardware Page Table walker enable
PWDirExt (30) - If 1, 4-th level implemented (MIPS64 only)
XK (28) - If 1, walker handles xkseg (MIPS64 only)
XS (27) - If 1, walker handles xsseg (MIPS64 only)
XU (26) - If 1, walker handles xuseg (MIPS64 only)
DPH (7) - Dual Page format of Huge Page support
HugePg (6) - Huge Page PTE supported in Directory levels
PSn (5..0) - Bit position of PTEvld in Huge Page PTE
