BIOS: Fix readOnly BIOS attributes

Previously, the readOnly property is true when without a D-Bus section in BIOS
JSON. Now, the readOnly property should be determined by a new readOnly field,
which should be introduced in the JSON. The checks are updated to ensure that
if there is D-Bus mapping then only D-Bus lookups are done.

Tested: test with json
