fix(libc): typecast expressions to match data type

This corrects the MISRA violation C2012-10.4:
Both operands of an operator in which the usual arithmetic conversions
are performed shall have the same essential type category.
The condition is explicitly checked against 0U, appending 'U' and
typecasting for unsigned comparison.

In spite of generic guidance for 3rd party libraries
(https://trustedfirmware-a.readthedocs.io/en/latest/process/coding-style.html#misra-compliance)
libc contains some MISRA-C fixes done by commit d5ccb754af86
("libc: Fix some MISRA defects") in 2021.
Also from history it is not clear where libc is
coming from that's why there is no way to fix
violation in base library.
