VisionFive 2: Add default compressed kernel address

Browse source 
The default U-Boot environment does not provide kernel_comp_addr_r and kernel_comp_size, needed when using a compressed kernel image. These variables are listed as mandatory in upstream U-Boot to allow this feature without needed user configuration: https://github.com/u-boot/u-boot/blob/master/doc/develop/distro.rst#required-environment-variables

The values are taken from the uEnv.txt shipped by StarFive's own Debian images, which does use a gzip-compressed kernel image hence proven to be valid. Adding those values to the U-Boot default environment allows them to be removed from the dedicated uEnv.txt and enables support for compressed kernel images independent of the used uEnv.txt or whether one is used at all.
