Add check of 4-byte address mode support when parsing SFDP 4bait. Some
flash will provide a 4bait table and the spi-nor core will convert the
address mode to 4-byte without checking whether it's actually supported
or not by the controller. For example, the 16M s25fs128s1 provides the
4bait and will be convert to 4-byte address mode, which makes it unusable
on hisi-sfc-v3xx on hip08 platform.

Add the check before convert the address mode when parsing the 4bait will
solve this issue.
