thorpej 2ecdd552dc Add the notion of "shadow registers" to the wdc driver. These shadow
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers.  Right now, the two
shadows are:

- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)

Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.
