target/loongarch: Add debug parameter with loongarch_page_table_walker()

Add debug parameter with function loongarch_page_table_walker(),
in debug mode it is only to get physical address. And It used in
future HW PTW usage, bit dirty and access will be updated in HW
PTW mode.

Also function loongarch_page_table_walker() is renamed as
loongarch_ptw() for short.
