Subject: [PATCH -next] PCI: dwc: Remove set but not used variable

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.
