This patch removes u8500_secondary_startup from _INIT section, there are two reason for this removal. 1. discarding such a small code does not save much, given the RAM sizes. 2. Having this code discarded, creates corruption issue when we boot smp-kernel with nr_cpus=1 or with single cpu node in DT.
