85xx: Add support for not releasing secondary cores via 'mp_holdoff'
Some OSes require that secondary cores not be initialized when they
are booted (eg VxWorks). By default when U-Boot is compiled with the
CONFIG_MP option all secondary cores are brought out of reset and held
in spinloops. Setting the "mp_holdoff" environment variable to 'yes'
or '1' will cause U-Boot to leave secondary cores in their default
state.
