rtp: rename sun4i-ts to sunxi-ts

sun4i-ts seems doesn't work fine with tslib. We want to see if sunxi-ts from new SDK is better. just at debug stage, and not recommend to use it now.

Some users complain about the MAC address keep changing after reboot. the CHIPID is unique from chip to chip, we may generate unique MAC address from it.
