mtd: spi-nor: sfdp: introduce smpt_map_id fixup hook

Browse source

Certain chips have inconsistent Sector Map Parameter Table (SMPT) data,
which leads to the wrong map ID being identified, causing failures to
detect the correct sector map.

To fix this, introduce smpt_map_id() into the struct spi_nor_fixups.
This function will be called after the initial SMPT-based detection,
allowing chip-specific logic to correct the map ID.

Infineon S25FS512S needs this fixup as it has inconsistency between map
ID definition and configuration register value actually obtained.
