Skylake Client CPU idle Power states (C-states)

intel_idle uses a NULL "enter" field in a cpuidle state
to recognize the invalid entry terminating a variable-length array.

Linux-4.0 added support for the system-wide "freeze" state
in cpuidle drivers via the new "enter_freeze" field.

The natural way to expose a deep idle state for freeze,
but not for run-time idle is to supply "enter_freeze" without "enter";
so we update the driver to accept such states.

A new BLK namespace "seed" device is created whenever the current seed
is successfully probed.  However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.

The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity.  Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

After commit 8d86e4fc ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),

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.

Current card detect probe process is that when driver finds a valid

Then host driver will know there's a valid card detect function.

Commit 8d86e4fc ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")

when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
