clk: qcom: ipq8074: SW workaround for UBI32 PLL lock

UBI32 Huayra PLL fails to lock in 5 us in some SoC silicon and thus it
will cause the wait_for_pll() to timeout and thus return the error
indicating that the PLL failed to lock.

This is bug in Huayra PLL HW for which SW workaround
is to set bit 26 of TEST_CTL register.

This is ported from the QCA 5.4 based downstream kernel.
