DW SDIO controller has external CIU clock divider controlled via register in the SDIO IP. Due to its unexpected default value (we expected it to divide by 1 but in reality it divides by 8) SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual is 12500000Hz) and works unstable (see STAR 9001204800). So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz by switching from the default divisor value (div-by-8) to the minimum possible value of the divisor (div-by-2) in HSDK platform code.
