device: Add fixed_io_range_flags() and helpers

Browse source 
Function fixed_io_resource() and alias io_resource() were
previously unused. Unlike previously, IORESOURCE_STORED flag
needs to be set by the caller, when necessary.

For fixed resources, fields alignment, granularity and
limit need not be initialised, as the resource cannot
be moved. It is assumed the caller provides valid base
and size parameters.
