target-mips: copy CP0_Config1 into DisasContext

In order to avoid access to the CPUMIPSState structure in the
translator, keep a copy of CP0_Config1 into DisasContext. The whole
register is read-only so it can be copied as a single value.

gt64xxx_pci: Add VMStateDescription

Add VMStateDescription for GT64120 PCI emulation used by the Malta
platform, to allow it to work with savevm/loadvm and live migration.

The entire register array is saved/restored using VMSTATE_UINT32_ARRAY
(fixed length GT_REGS = 1024).
