PCI: Identify Enhanced Allocation (EA) BAR Equivalent resources in sysfs

Browse Source 
Resource flags are exposed to userspace via the sysfs "resource" file.
lspci reads the sysfs file to determine resource properties.

Add a "BAR Equivalent Indicator" flag so lspci can distinguish between
[virtual] and [enhanced] resources.
