Gabor Juhos 0224bf502a clk: qcom: apss-ipq-pll: fix PLL rate for IPQ5018
[ Upstream commit c55f7ee2ec ]

According to ipq5018.dtsi, the maximum supported rate by the
CPU is 1.008 GHz on the IPQ5018 platform, however the current
configuration of the PLL results in 1.2 GHz rate.

Change the 'L' value in the PLL configuration to limit the
rate to 1.008 GHz. The downstream kernel also uses the same
value [1]. Also add a comment to indicate the desired
frequency.
