[][Critical][kernel][common][spinand][Add CASN support for SPI-NAND]

[Description]
Add CASN page support for SPI-NAND. CASN page has a full description
for SPI-NAND. Software driver can utililize it to address the whole
NAND chip. Also, it can handle ECC information as well. CASN page is
designed to solve the following problems:
1. Increasing size of SPI-NAND flash tables, which exist in
various drivers/mtd/nand/spi/*.c files.
2. Efforts on adding new SPI-NAND's flash tables.
3. Extract correct flash on-die ECC's bitflip numbers if it
supports advanced ECC status registers. The on-die ECC engine design
varies from vendor to vendor. CASN can transform them into unified
format.
4. A single Linux Kernel image can deal with most of SPI-NAND devices.
