*Changes in v3:
- split [PATCH v2 3/3] QE: assgin pins to QE-HDLC to two patches:
[PATCH v3 3/4] ls1043rdb: move USB mux config to config_board_mux
and [PATCH v3 4/4] qe: assgin pins to qe-hdlc.
*Changes in v2:
- Add new patch in patchset.QE: mask the codes not used for micro QE
- [PATCH v2 2/3] QE: add QE support on ls1043ardb
- get qe_immr and qe_immr directly instead of from qe_base
