Common function loongarch_check_pte() is to check tlb entry, return
the physical address and access priviledge. Also it can be used with

Use the 'vaddr' type.
will do in this way. It is simple and work on 32-bit guest vm on 64-bit

QEMU coding style prefers CamelCase.
Will do, how about the name MMUContext?

Use MMUAccessType access_type.
And fix loongarch_map_tlb_entry in a separate patch.
Will do this in a new patch.
That's the type from loongarch_get_addr_from_tlb and above.
