ddr: imx8m: ddrphy_train: add DDR4 support
There are DDR3L, DDR4 and LPDDR4 variants of the i.MX8M* SoMs used with
the NXP EVKs. So far, we only supported LPDDR4. For DDR4, we just need
different PHY training code. Encode the DRAM variant information
into a new dram_timing_info::dram_type and adjust the driver to make use
of it. The new CONFIG_FIRMWARE_IMX_DDR4_PMU_TRAIN Kconfig symbol can
co-exist with CONFIG_FIRMWARE_IMX_LPDDR4_PMU_TRAIN, allowing the same
barebox binary to target different memory types, provided board code
can determine what kind of DRAM is fitted.
