[RFC PATCH] mmc: sdhi: sys_dmac: check for all Gen3 types when whitelisting

Fixes: 26eb2607fa28 ("mmc: renesas_sdhi: add eMMC HS400 mode support")
Signed-off-by: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

So, adding HS400 support broke the detection here. I suggest we discuss
internally, if this kind of white listing is still needed, at all. Until
then, this patch makes things work again on H3 and M3-W.
