[v6,09/13] PCI: brcmstb: Don't conflate the reset rescal with phy ctrl

Commit Message

Add a "has_phy" field indicating that the internal phy has SW control that
requires configuration.  Some previous chips only required the firing of
the "rescal" reset controller.  This change requires us to give the 7216
SoC its own cfg_data structure.
