[ Upstream commit b7f8101d6e75fefd22c39624a30c9ed3d7a72463 ]
The smplsel bits for the SDMMC clock on Arria10 and Stratix10 platforms are
offset by 1 additional bit.
Add a new macro SYSMGR_SDMMC_CTRL_SET_AS10 for usage on the Arria10 and
Stratix10 platforms.
Fixes: 5611a5ba8e54 ("clk: socfpga: update clk.h so for Arria10 platform to
use")
