arm64: dts: mediatek: mt8192-asurada: Drop regulator-compatible property

BugLink: https://bugs.launchpad.net/bugs/2111953

[ Upstream commit d1fb968551c8688652b8b817bb081fdc9c25cd48 ]

The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It should not have been used for new
submissions such as the MT6315.

Drop the "regulator-compatible" property from the board dts. The
property values are the same as the node name, so everything should
continue to work.
