Add missing big-endian support when using two times iowrite32
to write 64 Bit.

Code for testing:
dev_info(&priv->pcid->dev, "CARDbUpdateTSF little endian before con.: 0x%016llx", qwTSFOffset);
qwTSFOffset = le64_to_cpu(qwTSFOffset);
dev_info(&priv->pcid->dev, "CARDbUpdateTSF little endian after con. : 0x%016llx", qwTSFOffset);
dev_info(&priv->pcid->dev, "CARDbUpdateTSF big endian: 0x%016llx", be64_to_cpu(qwTSFOffset));
Log
