The QSPI mailbox API function declarations (mbox_qspi_close and
mbox_qspi_open) in mailbox_s10.h were guarded by CONFIG_CADENCE_QSPI
preprocessor conditional. This prevented their prototypes from being
visible to code that may use the stub implementations when
CONFIG_CADENCE_QSPI is disabled.
Remove the CONFIG_CADENCE_QSPI preprocessor conditional so these functions
are always declared, regardless of the configuration. This avoids potential
build or linkage errors when stubs are used.

SPL checks for a magic word in the system manager's scratch
register to determine if an L2 reset has occurred. If detected,
SPL places all slave CPUs (CPU1–3) into WFI mode. The master
CPU (CPU0) then initiates a warm reset by writing to the RMR_EL3
system register and also enters WFI mode.
This warm reset flow is handled entirely within the HPS. The
function `socfpga_sysreset_request()` triggers the warm
reset, and upon SPL re-entry, the updated `lowlevel_init_soc64.S`
handles the necessary initialization.

Introduce a new symbol in the beginning of .data section in
the common ARMv8 linker script and use that as a reference
for data save and restore.
Previously, the code would rely on calculating the start of
the .data section address via data size, however, we observed
that the data size does not really reflect the SPL mapped
addresses.
In our case, the binman_sym section size was not included in
the data size, which will result in a wrong address for the
.data start section, which prevents us from properly saving
and restoring SPL data.
This approach skips the calculation for the starting address
of the .data section, and instead just defines the beginning
address of the .data section and calling the symbol as needed,
in which we think as a simpler and much more robust method.
