Add post_sfdp() hook to tweak flash config.

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.

This series opens doors for 5/.

Tested on sst26vf064b with atmel-quadspi SPIMEM driver.
