board/t104xrdb: Conditional workaround of errata A-008044
Workaround of Errata A-008044 was implemented without errata number and it is enabled by default. Errata A-008044 is only valid for T1040 Rev 1.0. So put errata number and make it conditional. Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
