imx8mp_evk: enable booting Image.gz and avoid extra memcpy
Add support for booting compressed kernel Image.gz by defining
kernel_comp_addr_r and kernel_comp_size in the default environment.
Set kernel_comp_addr_r to a high memory region (0x80000000) to provide
a dedicated decompression buffer, avoiding overlap between compressed
input and decompressed output.
Also adjust CONFIG_SYS_LOAD_ADDR from 0x40480000 to 0x40600000.
With TEXT_OFFSET=0, the kernel is relocated directly to loadaddr, so
separating decompression and execution regions is required to guarantee
safe decompression without additional copying.
