[PATCH] savagefb: Allocate space for current and saved register states

Allocate space for 2 register states: 'current' for the current state of
the hardware, and 'saved', to be used for restoring the hardware to a sane
state.  This is in preparation for the addition of state save and restore
hooks to make savagefb work together with the latest Xorg savage driver.
