Allow named IRQs to use corresponding specific handlers. If named IRQs are
used, at least an "sdcard" IRQ has to be specified by the platform. If
names are not used, an arbitrary number of IRQs can be provided by the
platform, in which case the generic ISR will be used for each of them.

Standardize the checks for multiple MMC header file inclusion,
including adding comments to terminating #endif's, and fixing
one incorrect comment.

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO
MFD cell driver. Now that the tmio_mmc driver has been split into a
core and a separate MFD glue, we can support SDHI natively without the
need to emulate an MFD controller. This also allows to support systems
with an on-SoC SDHI controller and a separate MFD with a TMIO core.

On some platforms (e.g. AP4EVB) the card detect pin of a slot is not
directly connected to the sdhi hardware, so that polling needs to be used
with tmio_mmc and card detection is handled in the platform code.
This patch allows to set tmio_mmc capabilities (to pass the
MMC_CAP_NEEDS_POLL flag) and exposes a get_cd hook for that purpose.

Boards can have different supplied voltages on different SD card slots. This
information has to be passed down to the SD/MMC driver.

This patch adds platform data with a function for power
control to the SDHI driver. The idea is that board specific
code can provide their own functions so power can be enabled
and disabled for the sd-cards.
