mtd: spi-nor: Regroup flash parameter and settings
The scope is to move all [FLASH-SPECIFIC] parameters and settings from 'struct spi_nor' to 'struct spi_nor_flash_parameter'. 'struct spi_nor_flash_parameter' describes the hardware capabilities and associated settings of the SPI NOR flash memory. It includes legacy flash parameters and settings that can be overwritten by the spi_nor_fixups hooks, or dynamically when parsing the JESD216 Serial Flash Discoverable Parameters (SFDP) tables. All SFDP params and settings will fit inside 'struct spi_nor_flash_parameter'. Move spi_nor_hwcaps related code to avoid forward declarations. Add a forward declaration that we can't avoid: 'struct spi_nor' will be used in 'struct spi_nor_flash_parameter'.
