sh-pfc: r8a7740: Hardcode the LCDC0 output

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.

gpio-rcar: Add RCAR_GP_PIN macro

Pins are numbered in the R-Car family documentation using a bank number
and a pin number in the bank. As the Linux pin number space is linear,
we need to flatten this by multiplying the bank number by 32 and adding
the pin number. The resulting number bear no directly visible
relationship  to the documentation, making it error-prone.

Add a RCAR_GP_PIN macro to convert from the documentation pin number
space to the linear Linux space.
