Artur Rojek 8b57ee7e01 sdhci_fsl_fdt: Provide more accurate clk calculation 
SDHCI controllers found in the QorIQ SoCs offer improved accuracy of
the clock frequency selection, compared to the SDHCI standard. Frequency
selection is performed using two divider registers, named prescaler and
divisor, according to the following formula:
frequency = base clock / (prescaler * divisor), where prescaler can be
bypassed (set to 1) and divisor permitted to take odd values.

Rather than depend on clock division precalculated by sdhci core, make
use of this property of the divider registers and achieve frequencies
closer to the ones requested.
