v4:
- s/spi_nor_read_reg/spi_nor_read_any_reg and
s/spi_nor_write_reg/spi_nor_write_any_volatile_reg to comply with Micron
and Cypress's naming scheme. Update documentation description on
spi_nor_write_any_volatile_reg.
- 2 new patches, the last ones, where I remove status polling on write
volatile registers
- collect R-bs
v3:
- queue patch: "mtd: spi-nor: Introduce templates for SPI NOR operations"
from
https://lore.kernel.org/lkml/20220304093011.198173-1-tudor.ambarus@microchip.com/
The dependency chain between patches was too long and hard to follow.

- Rework patch "mtd: spi-nor: core: Use auto-detection only once"
according to Pratyush's and Michael's suggestions
- Remove dev_dbg messge from spi_nor_read_id() method and let the callers
use their own message (detection, octal dtr enable/disable)
- detailed version changes in each patch

v2:
- Fix bug on octal dtr disable, s/nor->reg_proto/SNOR_PROTO_1_1_1,
because after disable the nor->proto is not yet updated
- update function/macros names to comply with Michael's rename series.
