ac22dde76c Revert "ARM: shmobile: streamline mackerel SD and MMC devices"
This reverts commit 626a645eb7.

This appears to be incompatible with
"ARM: shmobile: sh7372: Remove SDHI and MMCIF function GPIOs"

Reverting this change resolves the following build failure:

Both SDHI0 and SDHI2 power supplies on kzm9g can be switched on and off. In
the current version this is not used and the regulators are hard-wired to
"on." This patch switches SDHI0 and SDHI2 to proper fixed-voltage
regulators, using GPIOs to enable and disable them. Both ports shall
now be specifying the MMC_CAP_POWER_OFF_CARD MMC capability. Only SDHI0
has been tested with an SDIO card, since SDHI2 is a microSD slot.

b8b82b2983 ARM: shmobile: kzm9g: Reference DT implementation
Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.

Some notes:

* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
  - MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
  thus external devices may not be used. In particular,
  the SMSC ethernet device may not be used and thus
  NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
  which are needed for a working board:
  - SCIF (Serial)
  - CMT (Clock)
  - PFC (GPIO)

To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.

Includes fix by Thierry Reding to no longer use gic_handle_irq()

Includes fixes by Guennadi Liakhovetski for recent pinmux changes.

This patch fixes the following issues with SD and MMC interfaces on mackerel:
1. replace custom card-detection functions with standard GPIO CD API
2. resources don't have to be numbered
3. add SDHI interrupt names
4. remove OCR masks, where regulators are used
5. only specify SDHI CD interrupts on interfaces where a CD pin is present -
   SDHI0
6. don't instantiate an MMCIF device and initialise MMCIF pins if SDHI1 is
   selected
