arm64: dts: qcom: sc7280: herobrine: disable some regulators by default

Not all herobrine boards have a world facing camera or a fingerprint
sensor, disable the regulators that feed these devices by default and
only enable them for the boards that use them.

Similarly the audio configuration can vary between boards, not all
boards have the regulator pp3300_codec, disable it by default.
