phy: qcom-ufs: move decision of rate B calibration to ufs driver
Until now, the decision if phy calibration is according to rate A or
rate B values, was done in the phy driver. It made the phy dependent on
the ufs unipro which is unnecessary binding.
This change moves the decision into the ufs driver, and pass it through
a function parameter to the calibration routine in the phy driver.
