From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
commit f92ed0cd9328aed918ebb0ebb64d259eccbcc6e7 upstream.
SCI IP on RZ/G2L alike SoCs do not need regshift compared to other SCI
IPs on the SH platform. Currently, it does regshift and configuring Rx
wrongly. Drop adding regshift for RZ/G2L alike SoCs.
Fixes: dfc80387aefb ("serial: sh-sci: Compute the regshift value for SCI ports")
