We cannot go into sleep mode while Ethernet is actively DMAing.

* configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support

SSD1289 LCD. Initial checkin is just a clone of the

STM32F4Discovery's FSMC-based LCD interface. The Shenzhou
|

will need a completely need bit-banging interface; this

initial check-in is only for the framework.
