Devicetree-enabled boards should use proper regulators to control the
power of cards, not GPIOs, so let's remove this property. The regulator
properties are supported by the MMC core and are described in the
generic MMC document:
Documentation/devicetree/bindings/mmc/mmc.txt
Note that devicetree support for PXA platforms hasn't fully landed yet,
so this binding does not have any users at this point.

Call into mmc_of_parse() from pxamci_of_init(). As it needs a pointer to a
struct mmc_host, refactor the code a bit.
This allows all generic MMC properties to be set that are described in
Documentation/devicetree/bindings/mmc/mmc.txt. Reword the documentation
a bit to make that clear.
The "cd" and "wp" gpio lookups are removed as the lookup will now be
done by mmc_of_parse().

Some controllers immediately report that their internal clock is stable
after activating it even when the clock is not stable. When used in
conjunction with older/slower cards, this can result in:
mmc0: error -84 whilst initialising SD card
This flag allows documenting and thus working around such a hardware
defect.

We are about to add the support for ETR builtin scatter-gather mode
for dealing with large amount of trace buffers. However, on some of
the platforms, using the ETR SG mode can lock up the system due to
the way the ETR is connected to the memory subsystem.
In SG mode, the ETR performs READ from the scatter-gather table to
fetch the next page and regular WRITE of trace data. If the READ
operation doesn't complete(due to the memory subsystem issues,
which we have seen on a couple of platforms) the trace WRITE
cannot proceed leading to issues. So, we by default do not
use the SG mode, unless it is known to be safe on the platform.
We define a DT property for the TMC node to specify whether we
have a proper SG mode.

Following-up on the introduction of a new binding for the A64, this
introduces a system-control binding for the A10 as a replacement of
the sram-controller binding.
This change is motivated by consistency with the Allwinner literature,
that mentions system control over SRAM controller. Moreover, the system
control block is sometimes used for more than SRAM (e.g. for muxing
related to the ethernet PHY).
