ath10k/rtw89: make compile again after LinuxKPI changes

Both drivers are not yet attached to the build so this change is
for people currently trying them out.

In 96ab16ebab6319dce9b3041961b0ab6e20a4fecc the sys/rman.h include
was removed. In various wireless drivers we prefer to directly use
bus_dma functions rather than io* LinuxKPI once. In order to cast
the pointer we need sys/rman.h back for our native 'struct resource'
in their pci.c implementations.
Long-term we should consider providing some lkpi_-FreeBSD-specific
wrapper functions to avoid this problem.
