Fixes gcc '-Wunused-but-set-variable' warning:
drivers/pci/controller/dwc/pci-dra7xx.c: In function
'dra7xx_pcie_establish_link':
drivers/pci/controller/dwc/pci-dra7xx.c:142:6: warning: unused variable
'exp_cap_off'
[-Wunused-variable]
After 3af45d34d30c ("PCI: dwc: Centralize link gen setting"), variable
'exp_cap_off'
is never used. Remove it to avoid build warning.
