This reverts commit 04b8edad262eec0d153005973dfbdd83423c0dcb.
mx25l51245g and mx66l51235l have the same flash ID. The flash
detection returns the first entry in the flash_info array that
matches the flash ID that was read, thus for the 0xc2201a ID,
mx25l51245g was always hit, introducing a regression for
mx66l51235l.
If one wants to differentiate the flash names, a better fix would be
to differentiate between the two at run-time, depending on SFDP,
and choose the correct name from a list of flash names, depending on
the SFDP differentiator.

spi_nor_parse_sfdp(nor, nor->params);
passes for the second argument a member within the first argument.
Drop the second argument and obtain it directly from the first,
and do it across all the children functions. This is a follow up for
'commit 69a8eed58cc0 ("mtd: spi-nor: Don't copy self-pointing struct around")'

According to the mx25l12805d datasheet it supports using 4K or 64K sectors.
So lets add the SECT_4K to enable 4K sector usage.

The Macronix mx66u2g45g is a 1.8V, 2Gbit (256MB) device that
supports x1, x2, or x4 operation.
Tested on Pensando SoC hardware with a cadence quadspi controller
via drivers/spi/spi-cadence-quadspi.c, in x2 mode at 50MHz.
- random data write, erase, read - verified erase operations
- random data write, read/compare - verified write/read operations

The MX25R1635F is the smaller sibling of the MX25R3235F that is
already supported. It's only half the size (16Mb).
It was tested on the Kontron Electronics i.MX8MM SoM (N8010)
using raw read and write from and to the mtd device and
the 'flash_erase' command.

mx25u51245g is a mass production for new design and
replace mx66u51235f(phase out).
Validated by read, erase, read back, write and read back
on Xilinx Zynq PicoZed FPGA board which included
Macronix SPI Host (driver/spi/spi-mxic.c).

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.
