arm64: dts: qcom: msm8992-lg-bullhead: Enable regulators

Enable pm8994_s1, pm8994_l{26,29,30,32} regulators.
Use values from downstream kernel on bullhead rev 1.01.

NOTE: downstream kernel on angler rev 1.01 differences:
* pm8994_l29: regulator-min-microvolt = <2700000>
* pm8994_l{20,28,31}: use regulator-boot-on

Verification:
[    1.832460] s1: Bringing 0uV into 1025000-1025000uV
...
[    2.057667] l26: Bringing 0uV into 987500-987500uV
...
[    2.075722] l29: Bringing 0uV into 2800000-2800000uV
[    2.076604] l30: Bringing 0uV into 1800000-1800000uV
[    2.082431] l31: Bringing 0uV into 1262500-1262500uV
[    2.095767] l32: Bringing 0uV into 1800000-1800000uV
