arm64: dts: rockchip: Remove ethernet0 alias from the SoC dtsi for RK3399

Not all supported boards actually use the RK3399's built-in GMAC, while the
SoC TRM and the datasheet don't define some standard numbering in this case.
Thus, remove the ethernet0 alias from the RK3399 SoC dtsi file, and add the
same alias back to the appropriate board dts(i) files.

This is quite similar to the already performed migration of the mmcX aliases
from the Rockchip SoC dtsi files to the board dts(i) files.

arm64: dts: rockchip: fix supplies for pwm regulators

The supply-name for pwm-regualators is "pwm", so the property
needs to be pwm-supply, not vin-supply as in a number of boards.

In all cases changed here, the supplying regulator is always
an always-on fixed-regulator, so there will be no functional
change and only a change in the regulator hirarchy, as can be seen
for example in the regulator-summary.

arm64: dts: rockchip: Fix USB3 Type-C on rk3399-sapphire

Before this patch, the Type-C port on the Sapphire board is dead.
If setting the 'regulator-always-on' property to 'vcc5v0_typec0'
then the port works for about 4 seconds at start-up. This is a
sample trace with a memory stick plugged in:
1.- The memory stick LED lights on and kernel reports:
[ 4.782999] scsi 0:0:0:0: Direct-Access USB DISK PMAP PQ: 0 ANSI: 4
[ 5.904580] sd 0:0:0:0: [sdb] 3913344 512-byte logical blocks: (2.00 GB/1.87 GiB)

[ 5.951585] sdb: sdb1
[ 5.954816] sd 0:0:0:0: [sdb] Attached SCSI removable disk
2.- 4 seconds later the memory stick LED lights off and kernel reports:
[ 9.082822] phy phy-ff770000.syscon:usb2-phy@e450.2: charger = USB_DCP_CHARGER
3.- After a minute the kernel reports:
[ 71.666761] usb 5-1: USB disconnect, device number 2
It has been checked that, although the LED is off, VBUS is present.

If, instead, the dr_mode is changed to host and the phy-supply changed
accordingly, then it works. It has only been tested in host mode.

arm64: dts: rockchip: bulk convert gpios to their constant counterparts

Rockchip SoCs use 2 different numbering schemes. Where the gpio-
controllers just count 0-31 for their 32 gpios, the underlying
iomux controller splits these into 4 separate entities A-D.

Device-schematics always use these iomux-values to identify pins,
so to make mapping schematics to devicetree easier Andy Yan introduced
named constants for the pins but so far we only used them on new
additions.

Using a sed-script created by Emil Renner Berthing bulk-convert
the remaining raw gpio numbers into their descriptive counterparts
and also gets rid of the unhelpful RK_FUNC_x -> x and RK_GPIOx -> x
mappings:

/rockchip,pins *=/bcheck

arm64: dts: rockchip: add fan on rk3399-sapphire board

The Sapphire board has a 12V fan. So, adding it to the DTS.
There is no power supply directly connected, it needs the baseboard to
work.
If the board is used standalone then a hardware modification is needed.
On the Sapphire board there is an unpopulated resistor to connect it to
VBUS_TYPEC, which is usually 5V (too low) and can range up to 20V
(too high).
I tested it for a week connected to VCC_SYS which is 8.4V and proved to
be more than enough for the required cooling needs. This is the
connection described in the comment.

arm64: dts: rockchip: Fix microSD in rk3399 sapphire board

The microSD card slot in the Sapphire board is not working because of
several issues:
1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
and has a GPIO-based enable control.
2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
the DTS to just 3.0V because of the vmmc capability. This results in a
conflict from the mmc driver requesting an unsupportable voltage range
from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
3.- The card detect signal is non-working. There is a known conflict
with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
work. Adding the broken-cd attribute to the DTS fixes the issue.
