The merge of imx-spdif driver into fsl-asoc-card brought
new DT properties that can be used with the "fsl,imx-audio-spdif"
compatible:
* The "spdif-controller" property from imx-spdif is named "audio-cpu"
in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
with "audio-codec".
With an S/PDIF, codec drivers spdif_transmitter and
spdif_receiver should be used.
Driver imx-spdif used instead the dummy codec and a pair of
boolean properties, "spdif-in" and "spdif-out".
While backward compatibility is kept to support properties
"spdif-controller", "spdif-in" and "spdif-out", using new properties has
several benefits:
* "audio-cpu" and "audio-codec" are more generic names reflecting
that the fsl-asoc-card driver supports multiple hardware.
They are properties already used by devices using the
fsl-asoc-card driver.
They are also similar to properties of simple-card: "cpu" and "codec".
* "spdif-in" and "spdif-out" imply the use of the dummy codec in the
driver. However, there are already two codec drivers for the S/PDIF,
spdif_transmitter and spdif_receiver.
It is better to declare S/PDIF Tx and Rx devices in a DT, and then
reference them with "audio-codec" than using the dummy codec.
For those reasons, this commit updates in-tree DTs to use the new
properties:
* Rename "spdif-controller" property to "audio-cpu".
* Declare S/PDIF transmitter and/or receiver devices, and use them with
the "audio-codec" property instead of "spdif-out" and/or "spdif-in".
These modifications were tested only on an imx8mn-evk board.
Note that out-of-tree and old DTs are still supported.

Some SD Card controller and power circuitry has increased capacitance,
so the usual toggling of regulator to power the card off and on
is insufficient.
According to SD spec, for sd card power reset operation, the sd card
supply voltage needs to be lower than 0.5v and keep over 1ms, otherwise,
next time power back the sd card supply voltage to 3.3v, sd card can't
support SD3.0 mode again.
This patch add the off-on-delay-us, make sure the sd power reset behavior
is align with the specification. Without this patch, when do quick system
suspend/resume test, some sd card can't work at SD3.0 mode after system
resume back.

Different revision of i.MX8MN EVK boards may have different external
pull up registor design, some are enabled while some are NOT, to make
sure the WDOG_B pin works properly, better to enable internal pull up
resistor. Since enabling internal pull up resistor is NOT harmful and
having benefit of flexibility on different board design, just enable
it for all i.MX8MN boards; And schmitt input is NOT necessary for this
WDOG_B output pin, so remove it; Open drain outputs provide more
flexibility to a designer as they can be pulled-up to any voltage found
in the system, so enable it as well.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW
For level low interrupts, enable also internal pull up. It is
required at least on imx8mm-evk, according to schematics.
