TF-A GICv3 driver: Separate GICD and GICR accessor functions

This patch provides separation of GICD, GICR accessor
functions and adds new macros for GICv3 registers access
as a preparation for GICv3.1 and GICv4 support.
NOTE: Platforms need to modify to include both
'gicdv3_helpers.c' and 'gicrv3_helpers.c' instead of the
single helper file previously.

n1sdp: setup multichip gic routing table

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link, for now only dual-chip
is supported.

Whether or not multiple chips are present is dynamically probed by
SCP firmware and passed on to TF-A, routing table will be set up
only if multiple chips are present.

Initialize GIC-600 multichip operation by overriding the default GICR
frames with array of GICR frames and setting the chip 0 as routing
table owner.

n1sdp: add code for DDR ECC enablement and BL33 copy to DDR

N1SDP platform supports RDIMMs with ECC capability. To use the ECC
capability, the entire DDR memory space has to be zeroed out before
enabling the ECC bits in DMC620. Zeroing out several gigabytes of
memory from SCP is quite time consuming so functions are added that
zeros out the DDR memory from application processor which is
much faster compared to SCP. BL33 binary cannot be copied to DDR memory
before enabling ECC so this is also done by TF-A from IOFPGA-DDR3
memory to main DDR4 memory after ECC is enabled.

Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which
the entire DDR space cannot be accessed as DRAM2 starts in base
0x8080000000. So these macros are redefined for all ARM platforms.

plat/arm: introduce wrapper functions to setup secure watchdog

The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.

So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.
