The upstream commit 5f76895e4c71 ("serial: sh-sci: Fix late enablement of AUTORTS") inserted a new call to .set_mctrl(). However the backported version in stable (commit ad3faea03fdf ("serial: sh-sci: Fix late enablement of AUTORTS")) does not insert it at the same position.
This patch moves the added instructions back to where they should be according to the upsteam patch.
