[PATCH 2/2] Add 'sparse16550' support to PowerPC bootwrapper

[David Woodhouse]

The bootwrapper already handles a 'reg-shift' property on serial ports
and does the right thing. However, these ports really shouldn't be
claiming to be compatible with 'ns16550'. Introduce a new 'sparse16550'
type for them instead.
