Add a change_clock callback to allow drivers to update
device specific clock selections and control registers
when there is a change in clock.
Move the main part of sdhci_set_clock() to a new routine
which can be called by the glue drivers to do the sdhci
standard clock management.
Update the sdhci-s3c driver to use this to select the
appropriate clock source when clocks change.

The Samsung SDHCI controller block seems to fail to generate an
INT_DATA_END after the transfer has completed and the bus busy
state finished.
Changes in e809517f6fa5803a5a1cd56026f0e2190fc13d5c to use the
new busy method are the cause of the behaviour change.

Add a set_ios hook which is called when the SDHCI driver
is called to change parameters such as clock or card
width.

Some controllers do not provide clock information in their
capabilities (in the Samsung case, it is because there are
multiple clock sources available to the controller). Add hooks
to allow the system to supply clock information.

Some high speed capable controllers forget to set the high speed
capability bit. Make sure we enable the functionality anyway.

Add support for the scatter-gather DMA mode present on newer controllers.
As the mode requires 32-bit alignment, non-aligned chunks are handled by
using a bounce buffer.
Also add some new quirks to handle controllers that have bugs in the
ADMA engine.

Gracefully handle when the device is suddenly removed. Do a test read
and avoid any further access if that read returns -1.

Give the quirk for broken timeout handling a better chance of handling
more controllers by simply classifying the system as broken and setting
a fixed value.

The SDHCI interface is not PCI specific, yet the Linux driver was
intimitely connected to the PCI bus. This patch properly separates
the PCI specific portion from the bus independent code.
This patch is based on work by Ben Dooks but he did not have time
to complete it.

Otherwise it can only take the values 0/-1 which doesn't seem to

Some controllers have been designed on the assumption that all transfers
will be 32-bit aligned, both in start address and in size. This is not a
guarantee the SDHCI specification provides and not one we can provide.
Revert back to PIO for individual requests in order to work around the
hardware bug.

It is fully legal for a controller to start issuing data related
interrupts before it has signalled that the command has completed.
Make sure the driver actually can handle this.

The controller has a bit indicating that one of the higher bits (the
error bits) are set. A previous bug caused this bit to be masked, but
since that bug has been fixed we have to clear it explicictly.
