Add hibernate IO path for sdmmc(4). This requires some help from the sdmmc chipset driver, currently only implemented in sdhc(4), but mostly uses the regular path. sdhc(4) also needed the ability to perform IO while cold.

For DVACT_RESUME, let the children know we are ready *after* calling our own wakeup(). The wakeup() won't result in anything running now because DVACT_RESUME is running in "cold !=0, interrupts blocked, scheduler stopped", but it is idiomatically incorrect to inform your children you are ready before you are ready.

According to the SDIO Simplified Specification 3.0, a tuple length (aka link field) of 0 specifies an empty tuple body. This implies that a tuple length of 0 is actually allowed, so we don't need to error out if we encounter one. Seen on an SDIO-connected ath10k.

Correct the bitmask that returns the function count. We missed a bit and thus only supported 4 functions instead of 8.

First and foremost, avoid an obious race between two or more processes trying to get MMC commands through to the SD/MMC host controller via the emulated SCSI layer. This is achieved by ensuring exclusive access to the host controller for one process during any MMC command and during a sequence of commands at the sdmmc(4) layer.
