[U-Boot] [RFC 1/3] MIPS: bootm_qemu_mips.c: separate linux preparation code

[Gabor Juhos]

Move the preparation code into a separate function.
This is just a cosmetic change. The function will be
moved into bootm.c by a subsequent change.

This is compile tested only. I don't have suitable kernel
images for mips,mipsel,mips64,mipsel64 systems to try it yet.
