LT8668SX/LT8668SXC DP 转 eDPx/eDP 源码 设置说明
1 、 Global 配置， globalLT.h 文件：
#define CHIP_B05 DISABLED
//DISABLED,ENABLED
// LT8668SX U3 B03 设置 DISABLED
// LT8668SX U3 B05 设置 ENABLED
// LT8668SX C : Don't care
#define CHIP_SXC ENABLED
//DISABLED,ENABLED
// LT8668SX C chip 设置 ENABLED
// LT8668SX chip 设置 DISABLED
#define LT8668SXC_EVB DISABLED
//DISABLED,ENABLED
// 如果用 LT8668SXC demo 板 调试，设置 ENABLED ；否则设置 DISABLED
// 因为 LT8668SX C demo 板 的 DPRX 的 P/N 和 eDP 8lane TX 的 P/N 为了走线方便，有
swap ，在寄存器配置上需要跟着 swap
