To make the transition smoother introduced spi_nor_get_params() & spi_nor_set_params() APIs to get & set nor->params, added a new local variable (struct spi_nor_flash_parameter *params) to hold the return value of the spi_nor_get_params() function call and replaced all nor->params references with the "params". While adding multi-cs support in further patches the *params member of the spi_nor structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., nor->params[idx].
