Yes, I'll correct it in next patch.

I was using the latest boot-wrapper as the bootloader for test, I'll
add a compatible string "arm,psci" in v4.
We'll use u-boot on real hardware, the support for PSCI in our u-boot
is in progress.
We're intending to implement psci-0.1 at first, and psci-0.2 for the next step.

I'll test it on the SC9836 FPGA board before next submitting.
Thanks for your patient review.
