PR 5044 added incomplete kernel options for RPi4 which lead
to questions from "make oldconfig" during kernel build.
Fix this by processing RPi4 kernel config with oldconfig and
setting the missing options.

In order to reduce the number of images, I trimed to build only the most basic version which allows to boot all revsions and has all capabilities we need. (People can replace dtb from /usr/share/bootloader)
I also dropped some boards where I found shortcomings in the device tree which might be easy to solve but I can't test and they were not supported in earlier releases.
This adds a mapping for device trees which differ between vendor and mainline kernel and will therefore allow updates to new releases.
The old ones will be replaced by the new, or at least most appropriate (in case of RK3328 box devices), devicetrees in mainline kernel.
Besides a warning will be shown now if the device tree that the installation uses does not exist in the update tarball.
MiQi and Tinker devices have been merged to RK3288 device at some point after LE9.2 release.
This allows updating for them as well through mapping to the new RK3288 device.
While at that also drop the pointless check for kernel versions.
The default of 512k is too small at 192kHz/8ch, kodi can only get a
86ms buffer instead of the 200ms buffer it usually wants. That results
in occasional buffer underruns when playing media from local storage
which is uncached in kodi's default settings.
Increase the alsa buffer size to 1.2MB so kodi can get the audio buffer
size it likes to have.
