Some devices need writing values to VFE VBIF registers.
Add helper functions to do this.

Vincent Knecht
From: Vincent Knecht <vincent.knecht@mailoo.org>
The camera subsystem for the MSM8939 is the same as MSM8916 except with
3 CSID instead of 2, and some higher clock rates.
As a quirk, this SoC needs writing values to 2 VFE VBIF registers
(see downstream msm8939-camera.dtsi vbif-{regs,settings} properties).
This fixes black stripes across sensor and garbage in CSID TPG outputs.
Add support for the MSM8939 camera subsystem.

Ah you're right I see we are only doing this for new SoCs.

What is the benefit of enabling CAMSS on a board without any sensors
connected to the SoC? Likely the board specific change has to be removed.

This is not a board, it's a PMIC-related include file which just wires
the supplies.

docs don't mention the interrupt of csid0, but this soc is very old so
something might have gotten lost..

camss_ahb should be unnecessary, maybe ispif_ahb too

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: using specified base-commit 8566fc3b96539e3235909d6bdda198e1282beaed
If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
