Revert "arm: dts: an7581: set r_smpl for MMC in U-Boot"

On my AN7581 board, the same change in the Airoha ATF-2.10 source code
causes instability in eMMC reading. After the patch, in about 9 of 10
cases, ATF BL2 is unable to read FIP image from the eMMC flash. Thus
BL31 and U-Boot are unable to start.

Lets revert commit 7cb79f8d3d55 ("arm: dts: an7581: set r_smpl for MMC
in U-Boot") until the issue will be investigated.
