mtd: spi-nor: micron-st: Enable locking for n25q00
n25q00 uses the 4 bit Block Protection scheme and supports Top/Bottom
protection via the BP and TB bits of the Status Register.
Enable locking for n25q00. Tested with cirrus controller.

mtd: spi-nor: Enable locking for n25q128a11
As 4bit block protection patchset for some micron models are merged,
n25q128a11 also uses 4 bit Block Protection scheme, so enable locking
for it. Tested it on n25q128a11, the locking functions work well.

mtd: spi-nor: Enable locking for n25q512ax3/n25q512a
n25q512ax3 and n25q512a use the 4 bit Block Protection scheme.
Enable locking for both. Tested on n25q512ax3. The other is modified
following the datasheet.

mtd: spi-nor: Trim what is exposed in spi-nor.h
The SPI NOR controllers drivers must not be able to use structures that
are meant just for the SPI NOR core.

struct spi_nor_flash_parameter is filled at run-time with info gathered
from flash_info, manufacturer and sfdp data. struct spi_nor_flash_parameter
should be opaque to the SPI NOR controller drivers, make sure it is.

spi_nor_option_flags, spi_nor_read_command, spi_nor_pp_command,
spi_nor_read_command_index and spi_nor_pp_command_index are defined for the
core use, make sure they are opaque to the SPI NOR controller drivers.

Micron/ST definitions outside of core.c.
