IO signal voltage switching is used for UHS speed mode. After the
voltage switching, the card is in UHS mode and it's needed to
set 4bit bus width before any data transfer command.

The eSDHC is not compatible with SD spec well, so we need
to use eSDHC-special code to switch to SDR50 mode.
1. IO signal voltage switching, eSDHC uses SDHC_VS to switch
io voltage and it's needed to configure a global utilities
register SCFG_SDHCIOVSELCR(if it has) and SDHC_VS signal.

Freescale QorIQ QDS boards use different SDHC Adapter card types as below.
To support SDHC Adapter card type 1(eMMC card Rev4.5) HS200 mode, select
to use peripheral clock and add callbacks for signal voltage switching and
tuning block setting for eSDHC.

ADAPTER_TYPE_1 0x1
Add a signal voltage switching callback to let host use its own

Although eMMC spec does not require a delay between tuning cycles,
some hosts need it to avoid tuning failure.

Move pxamci to mmc slot-gpio API to fix interrupt request.
It fixes the case where the card detection is on a gpio expander, on I2C
for example on zylonite board. In this case, the card detect netsted
interrupt is called from a threaded interrupt. The request_irq() fails,
because a hard irq cannot

The driver prints if the data width is 8-bit but it's using a
binary OR instead of a binary AND so it will always report as
"is_8bit=Y" regardless of the flags in host->mmc->caps.

Drivers needs to export the OF id table and this be built into
the module or udev won't have the necessary information to autoload
the driver module when the device is registered via OF.
