From: Yang Xiwen <forbidden405@outlook.com>

The value defaults to 0 and is ignored by dw_mmc code, so the other
users are not affected.

Setting this explicitly fixes some weird reading error found on Hi3798MV200.

Fixes: 8a5dc8140e62 ("mmc: hi6220_dw_mmc: add compatible for HC2910 support")

Will do. It seems that this should also apply to hi3798cv200-dw-mshc. 
tests are needed from cv200 users.
