refactor(libc): clean up dependencies in libc

- Removing platform dependencies from libc modules.
- Replacing panicking with actual error handling.
- Debug macros are included indirectly from assert.h. Removing
"platform_def.h" from assert.h and adding "common/debug.h"
where the macros are used.
- Removing hack for fixing PLAT_LOG_LEVEL_ASSERT to 40.
Instead removing assert with expression, as this
does not provide additional information.

fix(gic600): implement workaround to forward highest priority interrupt

If the interrupt being targeted is released from the CPU before the
CLEAR command is sent to the CPU then a subsequent SET command may not
be delivered in a finite time. To workaround this, issue an unblocking
event by toggling GICR_CTLR.DPG* bits after clearing the cpu group
enable (EnableGrp* bits of GIC CPU interface register)
This fix is implemented as per the errata 2384374-part 2 workaround

GICv3: GIC-600: Detect GIC-600 at runtime

The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.

This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.
