ddr: imx8m: add missing DDR clock rates
ddrphy_init_set_dfi_clk() is called to translate a scalar clock rate
as specified by board code into PLL parameters, which are configured.
enum ddr_rate describes the possible DDR rates and so far
ddrphy_init_set_dfi_clk() supported all of them, except for 2600 and
2376 MHz, rendering these two rates unusable.
Fix this by adding support for them into ddrphy_init_set_dfi_clk.
