PCI/P2PDMA: Introduce configfs/sysfs enable attribute helpers
Users of the P2PDMA infrastructure will typically need a way for the user
to tell the kernel to use P2P resources. Typically this will be a simple
on/off boolean operation but sometimes it may be desirable for the user to
specify the exact device to use for the P2P operation.
Add new helpers for attributes which take a boolean or a PCI device. Any
boolean as accepted by strtobool() turn P2P on or off (such as 'y', 'n',
'1', '0', etc). Specifying a full PCI device name/BDF will select the
specific device.
