phy: phy-qcom-qusb2: Fix USB PHY power on sequence

Recent addition of support for SDM660 inadvertently broke USB PHY power
on sequence on RB1/RB2 and others with following error:

starting USB...
Bus usb@4e00000: QUSB2PHY pll lock failed: status reg = 0
qcom-qusb2-phy phy@1613000: PHY: Failed to power on phy@1613000: -16.
Can't power on PHY0
probe failed, error -16
No USB controllers found

The root cause was the addition of flag se_clk_scheme_default which was
configured correctly for SDM660 but incorrect for all other supported
SoC. Fix that by properly assignment as per upstream Linux driver.
