Fix a compilation error caused by pinconf_generic_parse_dt_config() not
being defined on !CONFIG_OF platforms by guarding the whole DT node
parsing code with #ifdef CONFIG_OF.
Defining a pinconf_generic_parse_dt_config() on !CONFIG_OF would have
been possible as well, but would have resulted in a larger code size on
!CONFIG_OF platforms (such as arch/sh).

The list of functions selected by the MOD_SEL2 register was missing
an entry. This caused all entries after this to modify the MOD_SEL2
register incorrectly.
This bug showed up when selecting i2c2_c pins on the Renesas Hurricane board.
This bug has been present since pinmux support was added for the
r8a7779 SoC by 881023d28b ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.

Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
The sh73a0 has an internal power gate on the VCCQ power supply for the
SDHI0 device that is controlled (for some strange reason) by a bit in a
PFC register. This feature should be exposed as a regulator.
As the same register is also used for pin control purposes there is no
way to achieve atomic read/write sequences with a separate regulator
driver. We thus need to implement the regulator here.

The r8a7740 has two LCDC units and two sets of LCDC output signals. By
default LCDC0 is routed to the LCD0 signals, and LCDC1 to the LCD1
signals. However, LCDC1 can be routed to the LCD0 signals by setting bit
MSEL6 in MSEL3CR (the LCD0 signals are further pinmuxed the usual way).
This could be configured by duplicating the LCD0 pin groups for LCDC1.
However, this would unnecessarily complicate the LCD pin groups, as no
r8a7740 board supported in mainline use such a configuration. Hardcode
the MSEL3CR MSEL6 bit to 0 for now.
