From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

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...

[bwh: Backported to 3.16:
- Use PINMUX_IPSR_MODSEL_DATA() instead of PINMUX_IPSR_MSEL()
- Adjust context]
