Commit 0b9f05f assumes that all platforms set RESET_TO_BL31 and

fix(intel): restore overlap-safe memcpy_s to prevent SoCFPGA BL2 hang

Previously, memcpy_s() in common/lib/libc was changed to
use memcpy/__builtin_memcpy to allow compiler optimizations
(FEAT_MOPS / inline sequences). While safe for most
platforms, this breaks SoCFPGA early boot because handoff data
can overlap in memory.

The change causes BL2 to hang, preventing UART initialization.

This patch restores overlap safety by replacing the memcpy call
with memmove/__builtin_memmove when available,
while preserving bounds checking.
This ensures SoCFPGA BL2 handoff functions correctly without
impacting other platforms.

fix(rk3576): shorten names to fit into the allocated space

The SCMI spec's CLOCK_ATTRIBUTES command specifies the `clock_name` part
of the return value as 16 long. Three of rk3576's names are a character
over, which GCC15 warns about truncating the NULL terminator. So shorten
the names a tiny bit to prevent this.
