Subject: [PATCH] Add new options to handle mirror selection better (#3325)

* Add new option UBOOT_MIRROR to select mainline U-Boot mirror

 - set to `github` to use mirror provided by GitHub, the same as `USE_GITHUB_UBOOT_MIRROR=yes`.
 - set to `gitee` to use mirror provided by Gitee, a Chinese git service.
 - leave it unset to use offical `source.denx.de`.

* Add GITHUB_MIRROR option

Usage similar to UBOOT_MIRROR.

* Add REGIONAL_MIRROR option

Chinese users (the main user of mirror options) can have use this one instead of configure many different options.
