nallino kernel: reduce size by removing unnecessary stuff

removes esp.:
 * lock debugging and debugging sysmbols for variables, etc.
 * support for i.MX3x, i.MX5x, i.MX6 non-ULL SoCs, i.MX8x
 * support for IPUv1, IPUv3, VPUs, GPUs
 * support for DVB and IR remote control modules

reduces (compressed) kernel size from almost 10 MB to just
under 6 MB. (uncompressed kernel is still almost twice as big as the
Rocko 4.9.88 kernel for 6ULL, though)
