JESD216 SFDP defines in BFPT methods to enter and exit the
4-Byte Address Mode. The flash parameters and settings that are
retrieved from SFDP have higher precedence than the static
initialized ones, because they should be more accurate and less
error prone than those initialized statically. Parse and favor the
BFPT-parsed set_4byte_addr_mode methods.

Some regressions may be introduced by this patch, because the
params->set_4byte_addr_mode method that was set either in
spi_nor_init_default_params() or later overwritten in default_init()
hooks, are now be overwritten with a different value based on the
BFPT data. If that's the case, the fix is to introduce a post_bfpt
fixup hook where one should fix the wrong BFPT info.
