There is some enhance about LoongArch mmu tcg emulation, add new
header file cpu-mmu.h and function loongarch_check_pte(). Function
loongarch_check_pte() can work on both TLB entry and pte entry.
This patchset mainly is code cleanup and enhancement, its main
purpose is to work for hardware page table walk emluation in future.
---
v1 ... v2:
1. Rename structure name pte_context with mmu_context, since it
can be extended to get DMW or DA mmu idx and window size
2. Add fine-grained tlb flush method
3. Fix some issues in function invalidate_tlb_entry() to flush tlb,
such as bitmap method with mmu idx, page size and address
calculation
