fix(intel): introduce a generic response error code
This patch will introduce a generic error code (0x3ff)
to be used in case where Secure Device Manager (SDM)
mailbox request is not failing (returns OK with no error
code) but BL31 instead wants to return error/reject
to the calling software. This value aligns with generic
error code implemented in SDM for consistency.
