Subject: [PATCH v2 0/6] mtd: spi-nor: move manuf out of the core - batch 2

v2:
- addressed all the comments
- all flash parameters and settings are now set in 'struct
spi_nor_flash_parameter', for a clearer separation between the SPI NOR
layer and the flash params.
Add post_sfdp() hook to tweak flash config. This series opens doors for 5/
from below.
In the quest of moving the manufacturer code out of the spi-nor core,
we want to impose the following sequence of calls:
1/ spi-nor core legacy flash parameters init:
spi_nor_default_init_params()
2/ MFR-based manufacturer flash parameters init:
nor->manufacturer->fixups->default_init()
3/ specific flash_info tweeks done when decisions can not be done just on
MFR:
nor->info->fixups->default_init()
4/ SFDP tables flash parameters init - SFDP knows better:
spi_nor_sfdp_init_params()
5/ post SFDP tables flash parameters updates - in case manufacturers get
the serial flash tables wrong or incomplete.
nor->info->fixups->post_sfdp()
The later can be extended to nor->manufacturer->fixups->post_sfdp() if
needed.
Tested on sst26vf064b with atmel-quadspi SPIMEM driver.
