Get physical address from virtual address is important for qmp command to
dump memory content. In TCG mode, it searches TLB tables firstly and
then do page table walker. In KVM mode, there are no TLB tables and page
table walker is used directly.
Here TLB tables searching is moved to directory tcg, and code about page
table walker is put in the common part so that it can be used in KVM mode
also.

v3 ... v4:
1. Remove stub definition with function loongarch_get_addr_from_tlb()
2. Use tcg_enable() when calling tcg specified function, stub definition
is not necessary for tcg specified function.
v2 ... v3:
1. Split patch 6 into two three small patches
2. Define tcg specified function from header file internals.h to
tcg/tcg_loongarch.h
v1 ... v2:
1. Remove CONFIG_TCG macro with file helper.h in patch 1
2. Refresh spelling issues in patch 5
3. Split original patch 4 into existing patch 4 and patch 5
4. Add !kvm_enabled() in function loongarch_map_address(), tlb entries
will not be searched in kvm mode
