885e268304 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.

e1b15b09a5 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
mentioned here:

1fe27d7135 refactor(gic): move GIC IIDR numbers
For the GIC power management we need to identify certain GIC
implementations, so we have the IIDR values for some Arm Ltd. GIC models
defined.
We will need those number elsewhere very soon, so export them to a
shared header file, to avoid defining them again.

0c9f91cf69 refactor(gicv3): rename GIC Clayton to GIC-700
The GIC IP formerly known as "GIC Clayton" has been released under the
name of "GIC-700".

Rename occurences of Clayton in comments and macro names to reflect the
official name.

e270e67511 gicv3: Do power management on Arm GIC-Clayton as well
The Arm GIC-Clayton IP has the same power management requirements as
the GIC-600, when it comes to powering up the redistributors before
using them.

Add the IIDR value to the existing list of implementations requiring
the power sequence.

8e570b71d8 drivers: arm: gicv3: auto-detect presence of GIC600-AE
This patch adds the IIDR value for GIC600-AE to the gicv3_is_gic600()
helper function. This helps platforms supporting this version of the
GIC600 interrupt controller to function with the generic GIC driver.

b4ad365a46 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.
