[PATCH v5 1/3] dt-bindings: mmc: mmc-spi-slot: Change voltage-ranges to uint32-matrix

[Frank Li <Frank.Li@nxp.com>]

According to common mmc core, voltages-ranges should be matrix.

Change from v4 to v5
- Change maxItems to 1

Not sure why it impact other mmc yaml's voltage-ranges.
Rob's answer:

It's a quirk of the tools. When decoding properties, the tools only know
all possible types. Types are global, not per binding. Sometimes it can
be figured out, but cases like this cannot be.
