bus/nes: Simplified a few related boards by Kasheng and Hosenkan.
- Reduced redundant code by making "kasing" device parent class for sglionk/sgboog. The latter are identical save for the extended register/address scrambling. - Eliminated hosenkan device altogether (mapper 182). It is identical to sglionk (mapper 114).
