Currently the usage of a second register range for MediaTek's MMC controller is seen only on a few platforms. However the driver tries to grab the register base regardless, and then ignores any errors. This makes all the other platforms that don't need it produce confusing error messages. Instead, make the driver only grab the register range for platforms that actually require it, and correctly handle the error. Also fix up the binding so that validation of the "reg" property is as strict as possible. Please take a look.
