ARM: shmobile: Koelsch legacy SDHI support

[PATCH 01/03] ARM: shmobile: Add r8a7791 legacy SDHI clocks [PATCH 02/03] pinctrl: sh-pfc: r8a7791: SD1_CLK fix [PATCH 03/03] ARM: shmobile: Add SDHI devices for legacy Koelsch

Add SDHI devices to the legacy Koelsch board support. While at it fix missing PFC bits for SDHI1 and also add legacy clocks. Each of the patches can be merged independently without compile failure, but all of them are required for correct SDHI run time operation on the Koelsch board. Next step is DTSI and DTS which will be handled in a separate series.
