The main differences:
- The initialization sequence requires an additional command (this was
already done)
- The layout of the CSD register and the way to compute the device
geometry from it changes
- The read and write commands parameter is a sector number instead of a
byte position

- The restrictions are now set by the sdhci bus and retrieved from there
by the DMAResources.
- Configure SDMA with the maximal available boundary check of 512K and
publish the corresponding DMA restrictions.
- dma_resource cannot be initialized implicitly as a member of
mmc_disk_driver_info because mmc_disk_driver_info is allocated with
malloc/free, not new/delete. So we now explicitly allocate and delete
it.
This allows reads and writes of more than a single block at a time.

The SDHCI spec also offers an "advanced DMA" mode where we can use
scatter-gather lists. It would allow to remove several of the DMA
restrictions, but hardware support for it is optional, so we need this
version anyway.
The geometry is retrieved on demand in the first read or write or in a
call to the get geometry or get device size ioctl. It is not possible to
retrieve it from the device initialization because that is called as
part of the mmc_bus scanning, which needs a specific sequence of
commands and keeps the bus locked to prevent drivers to insert their own
commands in the middle of that sequence.
TODO:
- Move the DMA restrictions definition to sdhci_pci and forward it up to
mmc_disk (which is the one creating the IOScheduler)
- Decide if we want to keep non-DMA support (probably should, but it
makes things more complex, because it uses virtual addresses)

Having the stack use the kernel address results in the kernel being

it's annoying when debugging as addresses need to be converted between
