Device tree provides option to specify the max freqency with property
"max-frequency" in dts and common parse function mmc_of_parse() will
parse it and use this value to set host->f_max to tell the MMC core

However, current sdhci driver will finally overwrite this value with

After commit 8d86e4fc

 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need to run the check of boarddata->wp_type/cd_type/max_bus_width

Current code only exclude the checking of wp_type for dt platform which
does not make sense.

This patch moves all non dt probe code into one function.
Besides, since we only support SD3.0/eMMC HS200 for dt platform, the
support_vsel checking and ultra high speed pinctrl state are also merged
into sdhci_esdhc_imx_probe_dt.

Then we have two separately probe function for dt and non dt type.
This can make the driver probe more clearly.

Current card detect probe process is that when driver finds a valid
ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION
which is set by default for all esdhc/usdhc controllers.
Then host driver will know there's a valid card detect function.

Commit 8d86e4fc ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")
breaks GPIO CD function for dt platform that it will return directly
when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms.
Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid
GPIO card detect.

This patch adds back this function and follows the original approach to
clear the quirk if find an valid CD GPIO for dt platforms.

errors. This is because after this commit 'host->data' is checked after
it has been cleared to NULL by omap_hsmmc_dma_cleanup().

Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked
making core layer not to be aware of DTO/DCRC errors. Because of this
any command invoked after DTO/DCRC error leads to a hang.

Fix this by checking for 'host->data' before it is actually cleared.

Regression fix for systemd getting confused about unknown connector state
after resume. Just stop setting the state to unknown, turned out to be a
silly idea anyway. What drivers imo really should do (and i915 still does
that) is forcing a full reprobe on resume to make sure connector changes
while suspended are caught. Most drivers seem to get this wrong. Otoh it
took us years to get fixes merged where some probe races resulted in

really low :(
