mtd: spi-nor: core: Init all flash parameters based on SFDP where possible

New flash additions that support SFDP should be declared with
PARSE_SFDP and with all the other flags that are not SFDP
discoverable.

Keep the old way of initializing the flash, until all the flashes
are converted to use either PARSE_SFDP or SPI_NOR_SKIP_SFDP.

Flashes that declare PARSE_SFDP do not have a roll-back mechanism
because if spi_nor_parse_sfdp() returns an error it means that either
BFPT is not supported, thus SFDP is not supported and the user didn't
correctly declared the flash_info entry, or some memalloc failed.
Either way we should return an error. The rest of the SFDP tables are
optional, if one of the optional SFDP tables fails, we just continue.
We would like to get rid of the default_init() hook, so the
spi_nor_manufacturer_init_params() is not called in the new sequnce
of flash initialization.

Split spi_nor_info_init_params() in spi_nor_init_default_params()
and spi_nor_no_sfdp_init_params(). spi_nor_init_default_params() is
called for all the flashes regardless if they support SFDP or not.
spi_nor_no_sfdp_init_params() is called just for the flashes that
do not define SFDP and initializes parameters and setting solely
based on flash_info data.
