The platform has variable interrupt types for GPIO interrupts, in
addition to having multiple lines per GPIO controller. Two interrupt
cells are required.

sd-det-hog should be cd-gpios, but when the mmc-spi-slot was added, the
"cd-" prefix was omitted and the collision with the hog was not noticed.
vio-enable-hog is just a regulator that can be modelled as such.

Recently the binding for regulator-fixed introduced preferred naming, in
the regulator-XvY format. Change the existing regulators to match this
pattern.

present in the devicetree. Add it.

GPIO controller 2 has the gpio-line-names property, but the two other
controllers do not. Add the property for these controllers too.

This has been merged as part of 7.1-rc1, so I've applied this series.
