mmc: sdhci-of-arasan: Add quirk to avoid unexpected interrupt msgs

On SD 2.00 cards we get lots of these messages:
"mmc0: Got data interrupt 0x00000002 even though no data operation was in progress"
By applying the SDHCI_QUIRK2_STOP_WITH_TC quirk, the messages no longer happen.

A single card claiming to be SD 3.00 compliant also generates the interrupts,
but since the card's manfacturing date is 2002 mar, it's unlikely to really be
SD 3.00. This card is a 8GB SanDisk 'SU08G' 8.0 (SDHC class 4).

This has been reported on Xilinx devices that also use the Arasan IP.
See https://patchwork.kernel.org/patch/8062871/

This has been tested on the Renesas RZ/ND-DB board with the RZ/N1 SoC. The
Arasan IP in this device is version 1.39a and uses a max SD clock of 50MHz and
does not support DDR modes.
