The R8A7790's dtsi file i2c0, i2c1, i2c2, and i2c3 nodes have clock
references to the mstp3_clks clock node, however these clocks are in the
mstp9_clks node.

The error was introducted in 72197ca7 ("ARM: shmobile: r8a7790:
 Reference clocks") which is in Simon's current development tree.

This patch fixes the following error:

of_clk_src_onecell_get: invalid clock index 31
i2c-rcar e6508000.i2c: cannot get clock
i2c-rcar: probe of e6508000.i2c failed with error -2

The r8a7790.dtsi file has four sdhi nodes which the first two have the wrong
resource size for their register block. This causes the sh_modbile_sdhi driver
to fail to communicate with card at-all.

Change sdhi{0,1} node size from 0x100 to 0x200 to correct these nodes
as per Kuninori Morimoto's response to the original patch where all four
nodes where changed. sdhi{2,3} are the correct size.

This bug has been present since sdhi resources were added to the r8a7790 by
8c9b1aa4 ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
templates") in v3.11-rc2.

Currently DT compatibility strings of both types can be found in the kernel
sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be
followed and the former one is preferred. This patch converts the SDHI
MMC driver and its users to the common standard. This is safe for now, since
ATM no real products are using this driver with DT.
