[PATCH 1/4] clk: qcom: gcc-glymur: Mark GCC AV1E AHB and XO clocks as critical

[Jagadeesh Kona]

The GCC AV1E AHB and XO clocks are required for AV1ECC register access.
Hence remove their clock modelling and add them to the GCC critical
clock list.

Fixes: efe504300a17 ("clk: qcom: gcc: Add support for Global Clock Controller")
