DM320: Regorganize LCD and TTB memory layout
Do not introduce any change for M:Robe 500 as it uses the two LCD frames
in non-obvious way.
Sansa Connect and Creative ZVM use only single front framebuffer.
Place TTB at DRAM end to minimize memory loss due to alignment.
Reserve as little as possible memory for the LCD frames.
On Sansa Connect this change extends audio buffer by 858 KiB.
