With Inline ECC enabled, the bottom 1/8 of DDR is reserved
for ECC parity bits and must not be used for general data address
allocation. Previously, the SPL bss and malloc addresses were allocated
inside this ECC parity region if the DDR size is 1GB.
This caused ECC hardware to detect stale or invalid parity bits,
leading to data correction attempts and DMA polling hangs or failures.
Fix this by relocating the malloc and bss to the usable 7/8 region of DDR
and is fully ECC-safe.
This change ensures reliable ddr address operation and
prevents unintended memory corruption.

Agilex5 FSBL is required to disable the power of unused peripheral SRAM
blocks to reduce power consumption.
Introducing a new power manager driver for Agilex5 which will be called
as part of Agilex5 SPL initialization process.
This driver will read the peripheral handoff data obtained from the
bitstream and will power off the specified peripheral's SRAM from the
handoff data values.

Use GPIO hogging method in device tree to set SDIO_SEL pin (portb3)
direction as output with value 0 after power-on reset.
This is to ensure stable 0V voltage reading from SDIO_SEL GPIO pin
after board init.

At present there is a hex value SPL_STACK which both determines whether
SPL has its own initial stack and the hex value of that stack.
Split off the former into SPL_HAVE_INIT_STACK with SPL_STACK depending
on that and only providing the latter.

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.
