For eMMC, this flag should be ignored but lets remove

The reset deassert time for the DP83TD510E is incorrectly set to
60000us, while the datasheet states that the minimum time required
after an hard reset is 30us (while 60ms is the time required for the
Power-On Reset after supply stabilization). The error probably arose
from the two timings being indicated by the same symbol (T2).
Lower the required time to 35us, aligning it to the value required for
the PHY to complete the reset AND to be able to accept the RMII master
clock. This saves ~60ms on boot if the MDIO driver is built-in.

The RESET GPIO pinmux should be part of MDIO bus node
so that they can be in the right state before the PHY
can be probed via MDIO bus scan.
The GPIO pin should be setup with PIN_INPUT so that
input circuitry is enabled in case software wants to
check pin status. Without this, incorrect status is shown
in /sys/kernel/debug/gpio.
Add GPIO reset for the Gigabit Ethernet PHY. As per
RTL8211F datasheet, reset assert width is 10ms and
PHY registers can be access accessed after 50ms of
reset deassert.

BeaglePlay SBC[1] has Texas Instrument's WL18xx WiFi chipset[2].
Currently, WLAN_EN is configured as regulator and regulator-always-on.
However, the timing and wlan_en sequencing is not correctly modelled.
This causes the sdio access to fail during runtime-pm power operations
saving or during system suspend/resume/hibernation/freeze operations.
This is because the WLAN_EN line is not deasserted to low '0' to power
down the WiFi. So during restore, the WiFi driver tries to load the FW
without following correct power sequence. WLAN_EN => '1'/assert (high)
to power-up the chipset.
Use mmc-pwrseq-simple to drive TI's WiFi (WL18xx) chipset enable
'WLAN_EN'. mmc-pwrseq-simple provides power sequence flexibility with
support for post power-on and power-off delays.
Typical log signature that indicates this bug is:
wl1271_sdio mmc2:0001:2: sdio write failed (-110)
Followed by possibly a kernel warning (depending on firmware present):
WARNING: CPU: 1 PID: 45 at drivers/net/wireless/ti/wlcore/sdio.c:123 wl12xx_sdio_raw_write+0xe4/0x168 [wlcore_sdio]

The beagleplay dts was using a bit-bang gpio mdio bus as a work-around
for errata i2329. However since commit d04807b806 ("net: ethernet: ti:
davinci_mdio: Add workaround for errata i2329") the mdio driver itself
already takes care of this errata for effected silicon, which landed
well before the beagleplay dts. So i suspect the reason for the
workaround in upstream was simply due to copying the vendor dts.
Switch the dts to the ti,cpsw-mdio instead so it described the actual
hardware and is consistent with other AM625 based boards

Prepare for pinctrl-single yaml binding and unify pin group node names.
Let's standardize on pin group node naming ending in -pins. As we don't
necessarily have a SoC specific compatible property for pinctrl-single.
I'd rather not add a pattern match for pins somewhere in the name for all
the users.
Trying to add matches for pins-default will be futile as on the earlier
SoCs we've already seen names like pins-sleep, pins-idle, pins-off and so
on that would need to be matched.
And as the node is a pin group, let's prefer to use naming -pins rather
than -pin as more pins may need to be added to the pin group later on.
