Add PFC support for the R8A7794 SoC including pin groups for some on-chip devices such as ETH, I2C, INTC, MSIOF, QSPI, [H]SCIF... Sergei: squashed together several patches, fixed the MLB_CLK typo, added IRQ4.. IRQ9 pin groups, fixed IRQn comments, added ETH B pin group names, removed stray new line and fixed typos in the comments in the pinmux_config_regs[] initializer, removed the platform device ID, took into account limited number of signals in the GPIO1/5/6 controllers, added reasonable and removed unreasonable copyrights, modified the bindings document, renamed, added changelog. Changes in version 5: - resolved rejects, refreshed the patch; - added Laurent Pinchart's ACK. Changes in version 4: - reused the PORT_GP_26() macro to #define PORT_GP_28(). Changes in version 3: - removed the platform device ID; - added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the CPU_ALL_PORT() macro. Changes in version 2: - rebased the patch.
