Gabor Juhos 82cc439976 ar71xx: remove obsolete '< KERNEL_VERSION(4, 4, 0)' check
Because the oldest supported kernel version on the ar71xx target is 4.4,
the condition that the kernel version is smaller than 4.4.0 is always
false. Remove the obsolete check from mach-rb4xx.c to clean up the code
a bit.
