bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.
