fix(libc): add const qualifier
This corrects the MISRA violation C2012-8.13:
A pointer should point to a const-qualified type whenever possible.
Added const qualifier to pointer.
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.
