ipod4g: Pull LCD framebuffer out of IRAM

The recent pcm_mixer changes caused us to overflow IRAM by a whopping 8
bytes. This can _probably_ be mitigated with some clever reworking but
we were clearly already on the hairy edge.

Future pending changes are likely to increase IRAM pressure so even if
we solve this issue the odds are it will reappear at a future point.

(the ipod4g's framebuffer is 5KB. This doesn't affect the mini2g as its
framebuffer is under 4KB, and the ipodcolor doesn't put its framebuffer
in IRAM at all)
