Support the single driver switch

Browse Source 
In order to select between the in-tree and OOT drivers for the single
driver, a cmdline parameter out-of-tree-drivers need be used. The
cmdline parameter out-of-tree-drivers will be set driver names that
these drivers will be used as the out of tree drivers. For example
"out-of-tree-drivers=ice,i40e,iavf", the OOT drivers ice, i40e, iavf
will be loaded by "insmod" command before udevd is started, and that
ensures that the OOT drivers will be loaded rather than the in-tree
drivers.

The default drivers will be the in-tree drivers if there is not
out-of-tree-drivers in the cmdline parameters or they are not set
correct.

1. Switch the single driver as the following step.
 a) ice
   * switch the ice driver to the OOT version
      out-of-tree-drivers=ice
   * switch the ice driver to the in-tree version
      remove ice from out-of-tree-drivers or set any value except ice
 b) i40e
   * switch the i40e driver to the OOT version
      out-of-tree-drivers=i40e
   * switch the i40e driver to the in-tree version
      remove i40e from out-of-tree-drivers or set any value except i40e
 c) iavf
   * switch the iavf driver to the OOT version
      out-of-tree-drivers=iavf
   * switch the iavf driver to the in-tree version
      remove iavf from out-of-tree-drivers or set any value except iavf
2. Switch the bundle driver as the following step.
   * switch the bundle drivers to the OOT version.
      out-of-tree-drivers=ice,iavf,i40e
   * switch the bundle drivers to the in-tree version
      out-of-tree-drivers=
    or
      remove out-of-tree-drivers from the boot commandline.
    or
      out-of-tree-drivers=aaa,bb,xx(any value except ice,i40e,iavf)
3. Switch any two ones.
   * switch ice and iavf to the OOT version.
       out-of-tree-drivers=ice,iavf
   * switch i40e and iavf to the OOT version.
       out-of-tree-drivers=i40e,iavf
   * switch to the in-tree version.
      just remove driver name from out-of-tree-drivers or set any value
      except ice, iavf and i40e.

Verification:
 Switch drivers between the OOT and in-tree drivers.
 - switch to the OOT drivers
   1. Add cmdline parameter out-of-tree-drivers=ice,iavf,i40e
   2. reboot
   can switch to the OOT drivers for ice, iavf and i40e.
 - switch to the in-tree drivers
   1. Remove cmdline parameter out-of-tree-drivers
   2. reboot
   can switch to the in-tree drivers for ice, iavf and i40e.
 - switch to the OOT ice driver(for iavf and i40e is same with ice)
   1. Add cmdline parameter out-of-tree-drivers=ice
   2. reboot
   can switch to the OOT driver for ice
 - switch to the OOT drivers for ice and iavf (for the combination of
   the other two drivers are same with this one. )
   1. Add cmdline parameter out-of-tree-drivers=ice,iavf
   2. reboot
   can switch to the OOT drivers for ice, iavf.
 - Set the cmdline parameter out-of-tree-drivers=ice,iavf,aaa
   It can switch to the OOT driver for ice and iavf.
