mmc: core: add NXP IW610 base ID and block size quirk
The NXP IW610 SDIO chipset identifies itself with a base card ID
(0x0214) during the initial MMC bus scan, whereas the WLAN function
reports a different ID (0x0215).
Like the IW61x, the IW610 requires MMC_QUIRK_BLKSZ_FOR_BYTE_MODE for
correct byte-mode block size handling. Since SDIO fixups are applied
before function devices are enumerated, the quirk must be associated
with the base card ID rather than the WLAN function ID.
Add the SDIO_DEVICE_ID_NXP_IW610_BASE definition and apply the required
fixup in the SDIO quirk table.
