arm: imx: imx8mm: correct unrecognized fracpll frequency
Frequency requested by ddrphy_init_set_dfi_clk from fracpll uses MHZ() macro, which expands the value provided to the Hz range without taking into account the precise Hz setting. This causes the frequency of 266 MHz not ot be found in the imx8mm_fracpll_tbl, since it is entered there with a precise Hz value. This in turn causes the boot hang in SPL, as proper DDR fracpll frequency cannot be determined. Correct the value in imx8mm_fracpll_tbl to match the one expanded by MHZ(266) macro, rounding it down to MHz range only.
