Subject: [PATCH 2/5] mmc: mtk-sd: don't hard-code interrupt trigger type

When using devicetree for configuration, interrupt trigger type
should be described in the dts file, not hard-coded in the C code.

The mtk-sd silicon in the mt7621 soc uses an active-high interrupt
and so cannot be used with the current code.

So remove the trigger and leave it to be set from devicetree.
