Subject: [PATCH V2 3/4] clk: qcom: videocc-sm8150: Add missing PLL config property

When the driver was ported upstream, PLL test_ctl_hi1 register value
was omitted. Add it to ensure the PLLs are fully configured.

Fixes: 5658e8cf1a8a ("clk: qcom: add video clock controller driver for SM8150")

Changes since v1:
 - Removed updating the test_ctl_hi_val, because as per latest HW recommendation
   its value is 0x0 which is same as PoR and hence no need to update it.
 - Keeping test_ctl_hi1_val same as before(v1).
