PCI: brcmstb: Use internal register to change link capability
The driver has been mistakenly writing to a read-only (RO)
configuration space register (PCI_EXP_LNKCAP) to change the
PCIe link capability.
Although harmless in this case, the proper write destination
is an internal register that is reflected by PCI_EXP_LNKCAP.
Thus, fix the brcm_pcie_set_gen() function to correctly update
the link capability.
