6.6-stable review patch. If anyone has any objections, please let me know.

From: Thomas Richard thomas.richard@bootlin.com
[ Upstream commit 063c938928dc80c2bfd66f34df48344db22e009b ]
During the resume sequence of the host, cdns_pcie_host_init() needs to be called, so set it global.
The dev function parameter is removed, as it isn't used.
