--------------------------------

[ Upstream commit f1de5880 ]

J7200 has the same PCIe IP as in J721E with minor changes in the
wrapper. J7200 allows byte access of bridge configuration space
registers and the register field for LINK_DOWN interrupt is different.
J7200 also requires "quirk_detect_quiet_flag" to be set. Configure these
changes as part of driver data applicable only to J7200.
