poplar: Decouple from plat/arm files 

plat/arm files should only be used by Arm platforms. If other platforms
use them, they create dependencies that can introduce problems when
updating Arm platforms.

This patch copies the needed code from Arm platforms so that poplar can
be independent from them.
