HTTPS support on WIMBOOT

[Rogner]

Hi Nikize

Sorry for the inconvenience and thanks for quick advice
Yes, you are right, it is not related to wimboot since it is used to create virtual filesystem on memory.

It is my fault that I consider I have enabled DOWNLOAD_PROTO_HTTS in general/config.h.
After enable the DOWNLOAD_PROTO_HTTPS, I could successfully chainboot via HTTPS.
Many thanks for your help
