[PATCH v2] ARM: shmobile: koelsch: Add support HSCIF1

[Nobuhiro Iwamatsu]

Koelsch can use HSCIF1 insetead of SCIF1 as serial port. But if we want to
use, we will need to disable the GPIO key and remodeling of the board.
Therefore status of hscif1 does not set the "okay".

 V2: Remove hscif1_clk from renesas,groups. This pin does not use.
