mb/intel/ehlcrb: Remove board ID detection via EC

Since there is no EC support on EHL CRB, this patch removes board
ID detection via EC (board_id.c & board_id.h) and its related
files. Temporarily removes variant_memcfg_config function in
romstage_fsp_param.c, will be added back when updating memory
configs later.
