[PATCH v1 1/1] phy: ti: tusb1210: Don't check for write errors when powering on

[Andy Shevchenko]

On some platforms, like Intel Merrifield, the writing values during power on
may timeout:

   tusb1210 dwc3.0.auto.ulpi: error -110 writing val 0x41 to reg 0x80
   phy phy-dwc3.0.auto.ulpi.0: phy poweron failed --> -110
   dwc3 dwc3.0.auto: error -ETIMEDOUT: failed to initialize core
   dwc3: probe of dwc3.0.auto failed with error -110

which effectively fails the probe of the USB controller.
Drop the check as it was before the culprit commit (see Fixes tag).
