clk: qcom: clk-alpha-pll: Add Pongo PLL

Add support for Pongo type of PLL clocks, used in Qualcomm SM8750 SoC.
Notable difference comparing to other PLLs is the need for calibration
for internally generated clock followed by wait_for_pll().  This is done
in configure call and at this time clocks are not yet registered, thus
wait_for_pll() cannot use clk_hw_get_name.  Locking during this
calibration requires much more time, thus increase the timeout in
wait_for_pll().
