[PATCH v2 2/2] mtd: spi-nor: macronix: Restore fallback parameters for MX25L12805D

[Cheng Ming Lin]

From: Cheng Ming Lin <chengminglin@xxxxxxxxxxx>

In a previous effort to drop flash_info fields and rely on SFDP, the
static size and no_sfdp_flags were removed from the MX25L12805D entry
(JEDEC ID 0xc22018).

At that time, the legacy MX25L12805D was already EOL and unavailable
for physical testing. Verification was inadvertently performed using
the newer MX25L12833F, which shares the same JEDEC ID but supports
SFDP. As a result, the probe succeeded during testing, leading to
the mistaken removal of the fallback parameters.

Since the actual MX25L12805D lacks SFDP support entirely, it strictly
requires these static parameters.

Restore .size = SZ_16M and .no_sfdp_flags = SECT_4K to this entry
to fix the probe failure for the legacy part.
