kernel/ipq806x: Restore kernel files for v6.1

as git will see the move and copy as a rename thus defeating the purpose.

Subject: [PATCH 4/9] clk: qcom: krait-cc: register REAL qsb fixed clock
With some tools it was discovered the real frequency of the qsb fixed
clock. While not 100% correct it's still better than using 1 as a dummy
frequency.
Correctly register the qsb fixed clock with the frequency of 225 MHz
instead of 1.
