phy: qcom: qmp-combo: correct bias0_en programming

Browse Source 
It seems the commit a2e927b0e5 ("phy: qcom-qmp-combo: Add sc8280xp
USB/DP combo phys") contained a typo for selecting bias0_en values.
First, bias0_en and bias1_en are expected to be symmetrical, and then
the vendor driver also uses `flipped : 0x3E : 0x15` statement for
bias0_en. Correct bias0_en programming to follow this.
