Add a flash driver intended to handle various flash devices connected over MSPI bus as long as they support JEDEC SFDP. This is an initial commit providing only basic operations in Octal I/O mode with some hard-coded values for Macronix MX25Ux series chips. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>

When CONFIG_FLASH_PAGE_LAYOUT is used, this driver will support that
|
|
API. By default the page size corresponds to the block size (65536).
|
|
Other options include the 32K-byte erase size (32768), the sector
|
|
size (4096), or any non-zero multiple of the sector size.
