There is still the issue that loud and small on some
EVBs. For mass production consistency, we need to
increase and put more delay in enable DAC steps.
The suggest from vendor, we need to use 50 us instead
of 20 us for the key step 2 and step 4, insert 20 us
in other every steps.
Therefore, the total delay in enable DAC is about:
50 * 2 + 20 * 16 = 420us
It looks okay.

Sometimes the regulator is shared between several devices, if target rate
and target voltage are equal to initial rate and iniital voltage , the
min_uV and max_uV of regulator will be always equal to zero, other devices
may set a low voltage.

If initial rate is greater than opp rate and initial voltage isn't qeual
to opp volatge, the opp voltage may too low for initial rate, so it's
inappropriate to update voltage when initial voltage isn't qeual to
opp volatge.
In order to solve this problem and consider that the regulator is shared
between several devices on some platforms, make the following two changes.
If the driver doesn't support to change frequency, the opp table should
contain an opp whose rate is geater than or equal to initial rate, so that
the voltage is enough for initial rate and the min_uV and max_uV of
regulator aren't equal to zero after update voltage.
If the driver supports to change frequency, let devfreq framework update
rate and voltage.

As a second global reset, the GRF is not reset, the iomux and
pull of PWM pin is still keeping, but PWM controller is reset,
PWM pin goes into input mode. However, the pull is still none
changed in kernel, which can cause voltage problems, so should
always keep the PWM pin pull down mode, with 0~50 μA power
increase.

Allow to use tunable delay before detecting card after card is inserted,
which either comes from firmware node, or comes from debounce value
passed on to mmc_gpiod_request_cd(). If the platform doesn't support
debounce, then we fall back to use the debounce period as the delay,
otherwise, it behaves the same as before that a HW debounce(if set) plus
a 200ms hardcode delay before detecting the card.

cd-gpios uses a fixed delay, 200ms, before detecting card after the card
is inserted. 200ms doesn't work for some platforms, so some host drivers
added their own properties for parsing that from DT, for instance,
dw_mmc and pxamci. That being said, it should also be tunable when using
cd-gpios.
