- Bump to the latest kernel v5.9.11.
- Switch to PSCI for bringing up the secondary CPUs.
- Update the instruction in the readme.txt to use the latest FVP v8
Foundation Platform 11.12 build 38, and to start 4 cores in SMP.

Hi,
Here is a first step to "modernize" the arm_foundationv8_defconfig. I think
turning on more than one core with PSCI makes sense. Let me know if this is ok
for you. Also, in the future I would like to switch to GICv3 but I am not there
yet.
Best regards,
Vincent.
