Subject: [PATCH v9 2/8] mtd: spi-nor: Convert macros with inline functions

In further patches the nor->params references in
spi_nor_otp_region_len(nor) & spi_nor_otp_n_regions(nor) macros will be
replaced with spi_nor_get_params() API. To make the transition smoother,
first converting the macros into static inline functions.
