Subject: [PATCH v2 03/10] arm64: dts: qcom: sdm845: Add the missing clocks on the dispcc

We're transitioning over to requiring the Qualcomm Display Clock
Controller to specify all the input clocks.  Let's add them for
sdm845.

NOTES:
- Until the Linux driver for sdm845's dispcc is updated, these clocks
  will not actually be used in Linux.  It will continue to use global
  clock names to match things up.
- Although the clocks from the DP PHY are required, the DP PHY isn't
  represented in the dts yet.  Apparently the magic for this is just
  to use <0>.

Changes in v2:
- Patch ("arm64: dts: qcom: sdm845: Add...dispcc") new for v2.
