cover Device Tree support for SH7751 based board

This is an updated version of something I wrote about 7 years ago. Minimum support for R2D-plus and LANDISK.
I think R2D-1 will work if you add AX88796 to dts.
And board-specific functions and SCI's SPI functions are not supported.

Yoshinori Sato (12):
sh: Add OF target boards.
sh: Update OF handling.
sh: SH4 OF support.
clk: SH7750 / 7751 clk driver.
drivers/irqchip: Add SH7751 and boards specific irqchip. drivers/pci: Add SH7751 PCI Host bridge driver.
clocksource: Update sh_tmu of handling. mfd/sm501: Add OF properties.
of: FDT vaddr support for SH.
serial/sh-sci: Fix earlyprintk / earlycon.
sh: target dts.
sh: OF defconfig.
