PCI: imx6: Remove unused assignment to variable ret
Previously, the maximum link speed was set following an "fsl,max-link-speed"
property read, and should the read failed, then the PCIe generation was
manually set to PCIe Gen1 and thus limiting the link speed to 2.5 GT/s.
Code refactoring completed in the commit 39bc5006501c ("PCI: dwc:
Centralize link gen setting") changed to the logic that was previously
used to limit the maximum link speed leaving behind an unused assignment
to a variable "ret".
Since the value returned from the of_property_read_u32() and stored in
the variable "ret" is never used in any meaningful way, and it's also
immediately reassigned in the code that follows, the assignment can be
removed.
