c1253b2445 fix(intel): update Agilex5 warm reset subroutines
Update the 'plat_get_my_entrypoint' assembly routine to
differentiate between cold reset, warm reset and SMP
secondary boot cores request.
Add secondary core boot request markup in BL31.
Perform CACHE flush/clean ops in case of warm reset request also.

7ac7dadb55 fix(intel): flush L1/L2/L3/Sys cache before HPS cold reset
This fix is to flush and invalidate the caches before cold reset.
Issue happen where Agilex5 hardware does not support the caches flush.
Thus software workaround is needed.

e264b55739 fix(intel): update memcpy to memcpy_s
memcpy does not check the dst_size which may
create vulnerable issue as it can overflow the buffer.
Using memcpy_s which check the dst_size will help to
reduce the risk. Also, this memcpy is always 4 bytes
each time.

7f7a16a6c0 fix(intel): update boot scratch to indicate to Uboot is PSCI ON
There is a use case where kernel requested ATF to power off/on only CPU0.
However, after ATF power off/on CPU0, CPU0 did not back into the state
to wait for ATF. Instead, CPU0 continue to reentry SPL boot sequence
because CPU0 is master/primary core. This causing the system reboot from
SPL again, while the slave core still in kernel.

To resolve this, ATF is set the boot scratch register 8 bit 17 whenever
it is a request from kernel to power off/on only CPU0. So, if this boot
scratch bit is set, CPU 0 will be able to put into a state to wait for
ATF.

c703d752cc fix(intel): fix ECC Double Bit Error handling
SError and Abort are handled in Linux (EL1) instead of
EL3. This patch adds some functionality that complements the
use cases by Linux as follows:

- Provide SMC for ECC DBE notification to EL3
- Determine type of reset needed and service the request in
  place of Linux
