[PATCH RFC 4/8] pinctrl: qcom: sm8750: Expose reference clocks

[Konrad Dybcio <konradybcio@kernel.org>]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

The gating toggles were moved to the TLMM register space on this
platform. They lived inside TCSR a generation prior and are back there
again a generation after.

Expose them, so that they can be consumed by other blocks.
