Subject: pinctrl: sh-pfc: r8a7791: Add missing HSCIF1 pinmux data

From: Sergei Shtylyov <[email protected]>

commit da7a692fbbab07f4e9798b5b52798f6e3256dd8f upstream.

The R8A7791 PFC driver was apparently based on the preliminary revisions of the user's manual, which omitted the HSCIF1 group E signals in the IPSR4 register description. This would cause HSCIF1's probe to fail with the messages like below:

sh-pfc e6060000.pfc: cannot locate data/mark enum_id for mark 1989 sh-sci e62c8000.serial: Error applying setting, reverse things back
sh-sci: probe of e62c8000.serial failed with error -22

Add the neceassary PINMUX_IPSR_MSEL() invocations for the HSCK1_E, HCTS1#_E, and HRTS1#_E signals...
