ddr: imx8m: add deprecation warnings for ddrphy_trained_csr
ddrphy_trained_csr and ddrphy_trained_csr_num are generated by the
spreadsheet, but are unused. Instead a default array with fixed values
is unconditionally used. Add a deprecation warning to alert to this
fact.
It seems GCC doesn't print this deprecation when using C99
designated initializers, but clang(d) does, so it's useful to have for
those using clangd in their editors.
