Subject: [PATCH] drivers: base: component: Allow more space for device name

Some drivers use <BDF>-<UUID> as the aggregate device name which uses
more than 20 chars, causing the status not to be aligned correctly.
Example for mei_gsc_proxy on LNL:

Before:
	aggregate_device name                                  status
	-------------------------------------------------------------
	0000:00:16.0-0f73db04-97ab-4125-b893-e904ad0d5464                bound

After:
	aggregate_device name                                            status
	-----------------------------------------------------------------------
	0000:00:16.0-0f73db04-97ab-4125-b893-e904ad0d5464                 bound

Give it 10 more chars for proper alignment.
