Subject: serial: sh-sci: Fix register offsets for the IRDA serial port

From: Laurent Pinchart <[email protected]>

[ Upstream commit a752ba18af8285e3eeda572f40dddaebff0c3621 ]

Even though most of its registers are 8-bit wide, the IRDA has two 16-bit registers that make it a 16-bit peripheral and not a 8-bit peripheral with addresses shifted by one. Fix the registers offset in the driver and the platform data regshift value.
