Add new Nokia build target and establish an arm64 build:
Platform: arm64-nokia_ixs7215_52xb-r0
HwSKU: Nokia-7215-A1
ASIC: marvell
Port Config: 48x1G + 4x10G
How I did it
- Change make files for saiserver and syncd to use Bulleseye kernel
- Change Marvell SAI version to 1.11.0-1
- Add Prestera make files to build kernel, Flattened Device Tree blob and ramdisk for arm64 platforms
- Provide device and platform related files for new platform support (arm64-nokia_ixs7215_52xb-r0).
