core: fix memory address comparison

Addresses are unsigned values. Subtracting address values results
in an unsigned value. Since qsort comparison function expects a signed
integer return value, the unsigned address subtraction value gets
signed and can produce a wrong result. This change overcomes the issue
by producing a +1/0/-1 signed value based on the address unsigned
values comparison.

Introduce CMP_TRILEAN() in util.h to implement the operation.

core: default enable program flow prediction on ARMv7 cores

Introduce CFG_ENABLE_SCTLR_Z to enable SCTLR[Z] from the generic boot.
SCTLR[Z] enables program flow prediction support from the core.

Early branch prediction may be unsafe against uncontrolled memory
prefetches that could hit some hard memory access control firewalls.
It is usually safer to enable after the mmu is enabled.

CFG_ENABLE_SCTLR_Z allows to use vanilla op-tee on development board
to exercises benchmark and performance tests over the op-tee system.

This feature is no expected on ARMv8 architectures and some recent
ARMv7 architectures since program flow prediction enable is tight to
mmu enable.

core: fix overlapping conditions of pagestore load areas

This change copies pagestore remaining part first, from any location to
its target destination before copying pagestore init part to target
destination. This prevents pagestore init copy to corrupt pagestore
remaining part at the location where bootloader loaded it.

As bootloader can load pagestore data anywhere in RAM, it is possible
that it loads it into an area overlapping with the area allocated by
the core to store effective pagestore. To prevent this, use memmove()
to copy the data instead of memcpy().
