Problem:
debug break gki10
Solution:
1, support amlogic_debug build to module, amlogic_debug module
includes debug_lockup, cpu_mhz and meson_atrace for now.
2, amlogic_debug some function still build in kernel but not break
gki10, for example: irq_check function on builtin kernel code,
module_debug, workqueue debug etc.
3, new config CONFIG_AMLOGIC_HARDLOCKUP_DETECTOR still builtin but
not break gki.
4, other functions for example iotrace still under developing
