A Samsung employee told me that the Exynos encryption data unit size is configurable
and also that it is set by the following code:

	hci_writel(ufs, PRDT_SET_SIZE(12), HCI_TXPRDT_ENTRY_SIZE);
	hci_writel(ufs, PRDT_SET_SIZE(12), HCI_RXPRDT_ENTRY_SIZE);

How about introducing a new macro that represents the TX PRDT entry size, the RX PRDT
entry size and the encryption data unit size?

Thanks,

Bart.
