mmc: core: add NXP IW61x base ID and block size quirk

Browse source

The NXP IW61x series SDIO chipset identifies itself with a base card ID
(0x0204) during the initial MMC bus scan, while the specific WLAN
function reports a different ID (0x0205).

To ensure that the MMC_QUIRK_BLKSZ_FOR_BYTE_MODE quirk is correctly
inherited by all SDIO functions (including Wi-Fi), it must be attached
to the base card ID at the core level.

Add the SDIO_DEVICE_ID_NXP_IW61X_BASE definition and apply the required
fixup in the SDIO quirk table.
