soc/amd/picasso/Kconfig: update help text for 2nd VBIOS ID detection
The help text for VGA_BIOS_SECOND_ID was outdated and from a time before
we found out that just looking at the CPUID doesn't reliably tell us on
which type of silicon we're running and which VBIOS file to pick, so we
had to use a different method. Update the help text to match what the
code does.
