clk_{un}prepare is mandatory for platforms using common clock framework.
Since this driver is used by SPEAr platform, which supports common clock
framework, add clk_{un}prepare() support for it.

This adds simple DT bindings for SDHCI SPEAr controller. It uses cd-gpios
from common mmc bindings.

This also fixes spear300-evb.dts with correct name for card detect binding.

This patch replaces normal calls to resource allocation routines
with devm_*() derivative of those routines. This removes the need
to free those resources inside the driver.

With the inclusion of following patch (59b5bc3929b37):
"mmc: sdhci: remove "state" argument from sdhci_suspend_host"

we get a compilation error for sdhci-spear:
drivers/mmc/host/sdhci-spear.c:283:2: error: too many arguments to function
‘sdhci_suspend_host’

This patch fixes this error.

This patch converts the drivers in drivers/mmc/host/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Currently if card_power_gpio is passed from platform data, it is acquired
and its value is either set or reset. After that we overwrite it with 1,
which is not required.

So, this patch removes the extra line which sets its value.
