Subject: [PATCH] spi: dt-bindings: mediatek: Set min size for 'mediatek,pad-select'

The minimum array length defaults to the same size as the maximum. For
'mediatek,pad-select', the example has a length of 2 and in-tree .dts
files have a length of 1, but the schema says the length must be 4.

There's currently no warning in the example because the schema fixups
are not handling this case correctly.
