mmc: Add concept of an 'embedded' SDIO device.
This is required to support chips which use SDIO for signaling/ communication but do not implement the various card enumeration registers as required for full SD / SDIO cards. mmc: sdio: Fix bug where we're freeing the CIS tables we never allocated when using EMBEDDED_SDIO mmc: Add max_blksize to embedded SDIO data Signed-off-by: San Mehat <san@google.com>
