We have hardware IOMMU support and this is totally unnecessary.
The given value is also unreasonable, it's too small and causes
kernel panic in some cases:
[ 5706.856473] sdhci-dwcmshc
fe310000.mmc: swiotlb buffer is full (sz: 28672 bytes), total 512 (slots), used 498 (slots)
[ 5706.864451] sdhci-dwcmshc
fe310000.mmc: swiotlb buffer is full (sz: 65536 bytes), total 512 (slots), used 464 (slots)
This parameter seems to be added by mistake, so remove it.
