ARM: shmobile: r8a7790: fix shdi resource sizes

commit d721a15c300c5f638a11573a6dd492158e737d6a upstream.

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
8c9b1aa41853272a ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
templates") in v3.11-rc2.
