fix(nxp-mmc): fix clk_rate and bus_width type

Both 'clk_rate' and bus_width members of the 'struct imx_usdhc_params'
are defined as integers, while their usages are unsigned int.
Therefore, change the type to unsigned int. This also helps to avoid
MISRA C-2012 Rule 10.3 violations when unsigned values are assigned to
signed variables.
