arm/km: introduce bootcount env variable and clean km_arm
This environment variable is used to set the bootcount address
for the kernel.
last_stage_init is not available for arm platforms. So the
calls to set_km_var and set_bootcount_addr are done in
misc_init_r.
Additionally some unneeded printouts were removed.
