Subject: [PATCH v4 00/11] mtd: spi-nor: Address mode discovery (BFPT method & current address mode)

This is a new version of the following patch sets:
https://lore.kernel.org/linux-mtd/20220411125346.118274-1-tudor.ambarus@microchip.com/
https://lore.kernel.org/linux-mtd/20230315034004.5535-1-Takahiro.Kuwano@infineon.com/

Changes in v4:
- consider the BFPT retrieved address mode as an enumeration,
  manufacturers could support different methods at the same time
- split renaming of set_4byte_addr_mode methods in several patches for
  better clarity
- have initializations in a single line, even if bypasses the 80 chars
  limit, as they are < 100 chars anyway
- new patches that introduce spi_nor_set_4byte_addr_mode() and handle
  spi_nor_restore()
- clean Takahiro's patch
