v3 cover Add basic support for Telechips TCC8xxx SoCs

I'll reply to this mail with a series of 7 patches that add basic support for Telechips TCC8xxx SoCs. This includes support for the TCC8000-SDK development board. Device drivers for UART, MMC, NAND, USB (host + gadget) are also available and will be posted in a second step.

This -v3 series addresses the issues found in the review of -v2.

Thanks,
Hans
