dt-bindings: Remove "status" from schema examples, again

There's no reason to have "status" properties in examples. "okay" is the
default, and "disabled" turns off some schema checks ('required'
specifically).

A meta-schema check for this is pending, so hopefully the last time to
fix these.

Fix the indentation in intel,phy-thunderbay-emmc while we're here.
