projects/WeTek_Hub: render GUI at 1080p for 4K output

Browse Source 
Issues with previous set of patches:
- at some 4K output resolutions GUI was rendered at 1080p and covered only 1/4 of screen due to not changed iWidth and iHeight parameters
- rendering GUI at 4K while playing high-bitrate 4K video caused stuttering

Changes introduced in this patch:
- rewrite platform_init to be aware of 4K resolutions passed by uboot in "hdmimode" parameter
- always set virtual framebuffer resolution to 1920x2160 (like Kodi does)
- remove Kodi patch to render GUI at 4K
- add Kodi patch (https://github.com/xbmc/xbmc/pull/10332) to upscale GUI when screen resolution is 4K

Subject: [PATCH] EGLNativeTypeAmlogic: Enable GUI free_scale when framebuffer
size is less than output resolution
For 4K output Kodi renders GUI at 1080p and this results in GUI covering only 1/4 screen.
This patch enables hardware upscaling if output resolution is greater than rendered GUI
resolution.
