Provide alternate board code for the marzen 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.

Patch eac036ef9e "ARM: shmobile: streamline mackerel SD and MMC devices"
made the use of the sh_mmcif_device variable for mackarel optional,
but the definition is always provided, causing a build warning.

arch/arm/mach-shmobile/board-mackerel.c:1120:31: warning: 'sh_mmcif_device'
	defined but not used [-Wunused-variable]

Marking the variable as __maybe_unused will do the right thing here.

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

When regulators are used with MMC devices, explicitly provided OCR masks
are ignored, they can be removed from platform data. Also switch SDHI0
from fixed regulator with hard-wired GPIO levels to a proper GPIO regulator
instance to enable dynamic voltage switching.

Switch SDHI0 and SDHI1 SD-card interfaces on armadillo800eva to using GPIO
card detection, which provides maximum power saving and automatically
selects IRQ or polling mode, depending on the CD GPIO capability.
