V2:
patch 1:
 - Change "depends on INPUT" to "depends on INPUT=y", because the
   compilation error still exists when "INPUT=m".
patch 2:
  - Use ls2k0500 as the fallback compatible;
  - Add ls2k2000 compatible.
patch 3:
 - Drop ls2k1000 compatible, for ls2k0500 is used as the fallback
   compatible.
patch 4:
  - Drop label;
  - Drop regmap property in syscon-reboot, for it's deprecated;
  - Add missing space.
