x86/split_lock: Move Split and Bus lock code to a dedicated file
Bus Lock Detect functionality on AMD platforms works identical to Intel.
Move split_lock and bus_lock specific code from intel.c to a dedicated
file so that it can be compiled and supported on non-Intel platforms.
Also, introduce CONFIG_X86_BUS_LOCK_DETECT, make it dependent on
CONFIG_CPU_SUP_INTEL and add compilation dependency of the new bus_lock.c
file on CONFIG_X86_BUS_LOCK_DETECT.
