Add a debounce parameter to the mmc_gpio_request_cd() function that
enables GPIO debouncing when set to a non-zero value. This can be used
by MMC host drivers to enable debouncing on the card detect signal.

Patch "mmc: sdhci: Add size for caller in init+register" changed the
interface for sdhci_pltfm_init, while patch "mmc: sdhci-sirf: add mmc
host sdhci-pltfm based driver for SiRF SoCs" added a new driver
with the old interface.
This changes the sirf driver to use the new interface, avoiding
one warning, and simplifying the init sequence. Since we're here
already, this also adds an error path for failed clk_prepare_enable.

With device core now able to setup the default pin configuration, the
call to devm_pinctrl_get_select_default can be removed. And the pin
configuration code based on the deprecated Samsung specific gpio
bindings is also removed.
