kernel: Use new symbol to deactivate MIPS FPU support

With kernel 5.4 the upstream kernel supports deactivating the FPU
support on MIPS. Use this new upstream feature instead of our older
patch which was removed when porting the kernel patches to kernel 5.4.

This way both options are set which should work for older kernel
versions and also new ones.
