resource: Handle resource flags properly

I/O resource flags consist of I/O resource types and modifier
bits. Therefore, checking an I/O resource type in 'flags' must
be performed with a bitwise operation.

Fix find_next_iomem_res() and region_intersects() that simply
compare 'flags' against a given value.

Also change __request_region() to set 'res->flags' from
resource_type() and resource_ext_type() of the parent, so that
children nodes will inherit the extended I/O resource type.
