逐行扫描型Memory LCD显存管理与emWin移植

因为Memory LCD 的特性，不能设置像素坐标，只能用缓存整体刷新。

所以对于Memory LCD来说，emWin移植仅与打点函数有关，这里用Sharp Memory LCD（ls013b7dh03）作为实例。

//LCD的显存，逐行扫描
//存放格式如下.
//[0]0 1 2 3 ... 16   
//[1]0 1 2 3 ... 16   
//[2]0 1 2 3 ... 16   
//[3]0 1 2 3 ... 16   
//[4]0 1 2 3 ... 16   
//[5]0 1 2 3 ... 16   
//[6]0 1 2 3 ... 16   
//[7]0 1 2 3 ... 16

...

//[127]0 1 2 3 ... 16
