ftrace: Add support for syscall function tracer
This patch adds support for syscall tracing in TEE core. It complements
existing ftrace support for user TAs via adding trace for syscalls that
are invoked by user TAs into the TEE core.
And after this patch ftrace will cover both TA and TEE core code. So lets
rename config option from CFG_TA_FTRACE_SUPPORT to CFG_FTRACE_SUPPORT.
It is optional to enable syscall trace via CFG_SYSCALL_FTRACE=y config
option in addition to CFG_FTRACE_SUPPORT=y config option.

core: arm32: generate system register access code
Replaces the hand crafted system register code in <arm32.h> and
<arm32_macros.S> with generated code based on arm32_sysreg.txt which is
extracted from the ARM Architecture Reference Manual.
The remaining hand crafted code for cp15 accesses is not covered by the
ARM Architecture Reference Manual.
A script is added to generate both assembly macros and static inline
functions to access the system registers.
