i2c: sh_mobile: add device tree support
This patch enables DT support for the IIC driver used on SH-based SoCs such as sh7722 and sh7724 among others as well as SH-Mobile SoCs such as sh7367, sh7377, sh7372, sh73a0 and r8a7740. Tested with out-of-tree DT support code on the sh7372 Mackerel board. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
