kerneldevice,generic: fix DRIVERS and SUBSYSTEMS checks

We were applying the DRIVERS check looking only at the single port
driver. Instead, we now lookup and cache all drivers found in the
device tree, and apply the loose DRIVERS check properly looking at all
of them.

We were applying the SUBSYSTEMS and SUBSYSTEM check looking at the
sysfs path and just hoping the subsystem we're looking for is included
in the path itself. Instead, we now lookup and cache all susystems
found in the device tree, and apply the loose SUBSYSTEMS check
properly looking at all of them.

E.g. we can now match SUBSYSTEMS="mhi_q" in the following device tree,
without needing it to be found in the sysfs path:

  looking at device '/devices/pci0000:00/0000:00:1b.0/0000:01:00.0/1001_00.01.00_MBIM/mhi_uci_q/mhi_MBIM':
    SUBSYSTEM=="mhi_uci_q"
  looking at parent device '/devices/pci0000:00/0000:00:1b.0/0000:01:00.0/1001_00.01.00_MBIM':
    SUBSYSTEMS=="mhi_q"
  looking at parent device '/devices/pci0000:00/0000:00:1b.0/0000:01:00.0':
    SUBSYSTEMS=="pci"
