PCI: Remove hybrid devres nature from request functions

Browse source

All functions based on __pci_request_region() and its release counter
part support "hybrid mode", where the functions become managed if the
PCI device was enabled with pcim_enable_device().

Removing this undesirable feature requires to remove all users who
activated their device with that function and use one of the affected
request functions.

These users were:
	ASoC
	alsa
	cardreader
	cirrus
	i2c
	mmc
	mtd
	mtd
	mxser
	net
	spi
	vdpa
	vmwgfx

all of which have been ported to always-managed pcim_ functions by now.

The hybrid nature can, thus, be removed from the aforementioned PCI
functions.

Remove all function guards and documentation in pci.c related to the
hybrid redirection. Adjust the visibility of pcim_release_region().
