fix(intel): solve agilex warm reset issue

Agilex warm reset not able to trigger due to the system not able to
detect the magic number. ATF only able to solve for boot core.
For secondary cores, Linux need to update psci driver to WFI
the cores in EL3. Original Linux WFI is EL1.
Thus causing secondary cores not working

fix(intel): update warm reset routine and bootscratch register usage

Agilex5 platform:
Boot scratch COLD6 register is meant for Customer use only.
So, use Intel specific COLD3 register with [5:2]bits to
determine the warm reset and SMP boot requests.
Also handle the unaligned DEVICE/IO memory store and load
in the assembly entrypoint startup code.

Agilex, Stratix10, N5X platforms:
Use only the LSB 4bits [3:0] of the boot scratch COLD6 register
to detect the warm reset request.

Thus adding this will remove the code update needed when

Also, it will have ARM_LINUX_KERNEL_AS_BL33 flag for each
platform in platform.mk. This will be easily to control
based on platform build.

fix(intel): update preloaded_bl33_base for legacy product

Update preloaded_bl33_base for legacy product for Yocto.

The Yocto Jenkins build was initially configured to build products
where the starting of the DDR is from 0x0000 0000. And if there is
no NS_image_offset set, the Jenkins is not able to acquire the correct
address offset to boot up the system. However, in the direct OS boot,
there is no issue as the user shall always include the address offset
during the compilation phase. Otherwise, the code shall execute the
default address offset. Besides that, this also provides the
flexibility to user to customize their SoC design by not restricted
to the default address.

SDMMC block size. It was changed due to the need when boot to Linux.
Kernel.itb size is big thus we have to increase the available reading
block size. Otherwise for normal U-boot and Zephyr it shall not be
reading a big block size to avoid "garbage" data.
