[PATCH v2 5/7] hw/arm/aspeed_ast27x0-fc: Replace error_abort with local errp

[Jamin Lin via <qemu-arm@nongnu.org>]

This patch introduces a local Error **errp = NULL and
replaces error_abort with errp in these paths.

This makes error handling more consistent with QEMU guidelines and avoids
using error_abort in cases where failure should not be treated as a
programming error.

Discussion:
object_property_set_link() can return false only when it fails, and it
sets an error when it fails. Since passing &error_abort causes an abort,
the function never returns false, and the return statement is effectively
dead code. If failure is considered a programming error, using
&error_abort is correct. However, if failure is not a programming error,
passing &error_abort is wrong, and errp should be used instead. This
patch follows the latter approach by replacing error_abort with errp.
