[ Upstream commit 7b3132ecefdd1fcdf6b86e62021d0e55ea8034db ] Since 25aaa75df1e6 SDMA driver uses clock rates of "ipg" and "ahb" clock to determine if it needs to configure the IP block as operating at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both clocks as IMX6UL_CLK_SDMA results in driver incorrectly thinking that ratio is 1:1 which results in broken SDMA funtionality. Fix the code to specify IMX6UL_CLK_IPG as "ipg" clock for SDMA, to avoid detecting incorrect clock ratio.
