accel/tcg: Unify user and softmmu do_[st|ld]*_mmu()

The prototype of do_[st|ld]*_mmu() is unified between system- and
user-mode allowing a large chunk of helper_[st|ld]*() and cpu_[st|ld]*()
functions to be expressed in same manner between both modes. These
functions will be moved to ldst_common.c.inc in a following commit.
