This patch disable the ITAPDLYENA bit for ITAP delay value zero.
As per IP design, it is recommended to disable the ITAPDLYENA bit
before auto-tuning.
Also disable OTAPDLYENA bit always as there is one issue in RTL
where SD0_OTAPDLYENA has been wrongly connected to both SD0 and SD1
controllers. Hence it is recommended to disable OTAPDLYENA bit always
for both the controllers.
