From: Pawel Laszczak <pawell@cadence.com>

Fixes issue with priority of operator. Operator "|" priority is
higher then "? :".
To improve the readability the operator "? :" has been replaced with
"if ()" statement.

Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver")
Signed-off-by: Pawel Laszczak <pawell@cadence.com>

Changelog:
v2:
- changed the commit log
- added separate "if" statement to improve readability
