core: add plat_primary_init_early()

Adds plat_primary_init_early() which replaces plat_cpu_reset_late().
plat_cpu_reset_late() was called for each cpu, but
plat_primary_init_early() is only called on the primary cpu.

In practice that's not a problem (except for plat-stm, more on that
later) since all the platform specific plat_cpu_reset_late() only does
something if get_core_pos() returns 0, that is on the primary cpu.

On plat-stm SCR is now updated in plat_cpu_reset_early() instead.

This patch is needed because ASLR may relocate OP-TEE to a virtual base
address which differs from the physical base address. This means that
it's not possible to execute C code before MMU has been enabled.
