clk: qcom: gcc-msm8994: Remove NoC clocks
Just like in commit05cf3ec00d
("clk: qcom: gcc-msm8996: Drop (again) gcc_aggre1_pnoc_ahb_clk") adding NoC clocks turned out to be a huge mistake, as they cause a lot of issues at little benefit (basically letting Linux know about their children's frequencies), especially when mishandled or misconfigured. Adding these ones broke SDCC approx 99 out of 100 times, but that somehow went unnoticed. To prevent further issues like this one, remove them. This commit is effectively a revert of74a33fac3a
("clk: qcom: gcc-msm8994: Add missing NoC clocks") with ABI preservation. Fixes:74a33fac3a
