[U-Boot] Change of NDS32 Custodian

[Macpaul Lin]

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 at 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
