Resolve signed-unsigned comparison issues
A recent commit 030567e6f51731982a7e71cbd387de93bc0e35fd added U()/ULL()
macro to TF constants. This has caused some signed-unsigned comparison
warnings / errors in the TF static analysis.
This patch addresses these issues by migrating impacted variables from
signed ints to unsigned ints and vice verse where applicable.
