Merge branch 'clk-qcom-sdm845' into clk-next

* clk-qcom-sdm845:
  clk: qcom: Export clk_fabia_pll_configure()
  clk: qcom: Add video clock controller driver for SDM845
  dt-bindings: clock: Introduce QCOM Video clock bindings
  clk: qcom: Add Global Clock controller (GCC) driver for SDM845
  clk: qcom: Add DT bindings for SDM845 gcc clock controller
  clk: qcom: Configure the RCGs to a safe source as needed
  clk: qcom: Add support for BRANCH_HALT_SKIP flag for branch clocks
  clk: qcom: Simplify gdsc status checking logic
  clk: qcom: gdsc: Add support to poll CFG register to check GDSC state
  clk: qcom: gdsc: Add support to poll for higher timeout value
  clk: qcom: gdsc: Add support to reset AON and block reset logic
  clk: qcom: Add support for controlling Fabia PLL
  clk: qcom: Clear hardware clock control bit of RCG

Also fixup the Kconfig mess where SDM845 GCC has msm8998 in the
description and also the video Kconfig says things slightly differently
from the GCC one so just make it the same.
