qemu: Add addition environment space to boot loader qemu-system-mips
The qemu mips malta base board boot loader uses environment strings with a max length of 256 bytes which is not long enough to accommodate a long NFS path in addition to the normal kernel boot command line arguments. The solution is to expand the environment string length to 1024 bytes.

1qemu: Add addition environment space to boot loader qemu-system-mips

3Upstream-Status: Inappropriate - OE uses deep paths

5If you create a project with very long directory names like 128 characters
6deep and use NFS, the kernel arguments will be truncated. The kernel will
7accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
8to only 256 bytes. This patch expands the limit.
