Subject: [PATCH AUTOSEL 4.4 017/174] pinctrl: sh-pfc: sh7734: Remove bogus IPSR10 value

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit 4d374bacd7c9665179f9752a52d5d602c45d8190 ]

The IP10[5:3] field in Peripheral Function Select Register 10 has a
width of 3 bits, i.e. it allows programming one out of 8 different
configurations.
However, 9 values are provided instead of 8, overflowing into the
subsequent field in the register, and thus breaking the configuration of
the latter.

Fix this by dropping a bogus zero value.
