tcg: Split out target/arch/cpu-param.h For all targets, into this new file move TARGET_LONG_BITS, TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS, TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES. Include this new file from exec/cpu-defs.h. This now removes the somewhat odd requirement that target/arch/cpu.h defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the bulk of the includes within target/arch/cpu.h to the top.

target/mips: Support variable page size Traditionally, MIPS use 4KB page size, but Loongson prefer 16KB page size in system emulator. So, let's define TARGET_PAGE_BITS_VARY and TARGET_PAGE_BITS_MIN to support variable page size.
