mtd: spi-nor: macronix: Add post_sfdp fixups for Quad Input Page Program

Browse Source 
Although certain Macronix NOR flash support the Quad Input Page Program
feature, the corresponding information in the 4-byte Address Instruction
Table of these flash is not properly filled. As a result, this feature
cannot be enabled as expected.

To address this issue, a post_sfdp fixups implementation is required to
correct the missing information.
