Intel-SIG: commit a39c7cd0 dmaengine: idxd: removal of pcim managed mmio mapping.
Incremental backporting patches for DSA/IAX on Intel Xeon platform.

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

The devm managed lifetime is incompatible with 'struct device' objects that
resides in idxd context. This is one of the series that clean up the idxd
driver 'struct device' lifetime. Remove pcim_* management of the PCI device
and the ioremap of MMIO BAR and replace with unmanaged versions. This is
for consistency of removing all the pcim/devm based calls.
