drivers_managed-pc: simplification

Browse Source 
This patch removes the former use of ram_fs, fs_rom, and fs_report from
the subsystem and uses a report_rom instead. The fs-based reporting was
introduced to accommodate automatically instantiated usb_block drivers,
which turned out to be impractical for the sculpt scenario.
