commit 74f330bceaa7b88d06062e1cac3d519a3dfc041e upstream.
Since commit 30832ab56 ("mmc: sdhci: Always pass clock request value
zero to set_clock host op") was merged, esdhc_set_clock starts hitting
"if (clock == 0)" where ESDHC_SYSTEM_CONTROL has been operated. This
causes SDHCI card-detection function being broken. Fix the regression
by moving "if (clock == 0)" above ESDHC_SYSTEM_CONTROL operation.

1ms is enough for hardware to change the clock to stable.
100ms is too long in the tasklet.

sdhci-esdhc-imx does not need SDHCI_QUIRK_NO_CARD_NO_RESET.
Make it OF-specific.

It can be worked around using a GPIO which will be done for i.MX later.

Put everything which can be shared between the OF and platform version
of this driver into a local .h file.
