libc: Import strtoll from FreeBSD project
From commit: 21571b1d140ae7bb44e94c0afba2ec61456b275b
The coding guidelines[1] in TF-A forbid the use of ato*() functions
in favour of strto*(). However, the TF-A libc does not provide an
implementation of strto*(), making this rule impossible to satisfy.
Also made small changes to fit into TF-A project. Added the source
files to the libc makefile
