[U-Boot] Change of NDS32 Custodian

Hi,

Here is a short announcement about a change in the U-boot NDS32 custodian.

I have no longer working in Andes Technology Corporation and cannot provide the community the best support on NDS32 architecture. Kuan-Yu Kuo (a.k.a. Ken Kuo) will be the next custodian of u-boot-nds32 branch.

Thanks for the great support and co-working guide from Wolfgang, Tom, Po-Yu Chuang, Mike, Marek and many people. Thanks for your help which made the u-boot porting work of NDS32 architecture becomes the first open source mainline contribution of NDS32.

The official custodian e-mail of NDS32 will be changed to "uboot@andestech.com". Ken will send the patchwork permission request, patches to MAINTAINERS file, and update the U-boot Wiki later.

Thanks all!

Best Regards, Macpaul Lin
