I'm not too happy about the restart handler here: 

+#define RESCNT2 IOMEM(0xe6188020)
+static void sh73a0_restart(enum reboot_mode mode, const char *cmd)
+{
+       /* Do soft power on reset */
+       writel((1 << 31), RESCNT2);
+}

I see that you have the same thing in other SoCs, but I'd really want to
see this done properly at some point and likely won't take future patches
doing the same thing.

Please have a look at drivers/power/restart for how other platforms do
this. You probably need to add a device node for whatever IP block
holds the reset register and then have a driver. What exactly this
driver should look like depends of course on what other registers are
part of this block.
