[PATCH v2] mtd: mchp23k256: use SPI match data for chip caps

[Pengpeng Hou]

The driver stores chip capacity information in both the OF match table
and the SPI id table. Probe currently uses of_device_get_match_data(),
so a non-OF SPI modalias match falls back to mchp23k256_caps even when
the SPI id table selected a different part.

Use spi_get_device_match_data() so SPI id-table driver_data is consumed
when OF match data is absent. This keeps the existing default fallback
while avoiding the wrong MTD geometry for id-table-only matches.
