    ARM: dts: imx6sx: Specify IMX6SX_CLK_IPG as "ipg" clock to SDMA · afac6100

    Since 25aaa75d 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 IMX6SX_CLK_SDMA results in driver incorrectly thinking that
    ratio is 1:1 which results in broken SDMA funtionality. Fix the code
    to specify IMX6SX_CLK_IPG as "ipg" clock for SDMA, to avoid detecting
    incorrect clock ratio.
