Zbigniew Bodek e559c86d77 Workaround missing machine_resource_init in BSD initialization 
BSD compatibility is not optional for the kernel to build, however
platform dependent portion of this configuration, machine_resource_init(),
which is called by nexus_init() is implemented only in the platform
specific library for HiSilicon chips (libhi35xx_bsp.a).
Workaround lack of this library, so that the kernel can be built
for other platforms as well, by excluding it from the compilation.

This change should be removed as soon as the appropriate function
is implemented for other platforms.
