Since slot-gpio uses devm_* managed functions in mmc_gpio_request_cd()
now, we can remove those mmc_gpio_free_cd() call from host drivers'
.probe() error path and .remove().

Enable the quirk SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN since
SD_CAPABILITIES_1[15:8](BASE_FREQ) can't get correct base clock value.
It returns a fixed pre-set value like 200 on some sdhci-pxav3 based
platforms like MMP3 while return 0 on the other sdhci-pxav3 based
platforms.  So we enable the quirk and get the base clock via function
get_max_clock. Also add get_max_clock.

Tested on OLPC XO-4/MMP3, where the card detection pin for one of
the controllers is a sideband GPIO.  The third cell in the cd-gpios
property controls whether the GPIO is active high/active low.

(Also, pass host_caps2 through from platdata to the mmc host.)

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.

Drop the "state" argument from sdhci_suspend_host.  Its only user is the
PCI glue;  this allows to move all SDHCI glues to use dev_pm_ops instead.
