arm64: zynqmp: Describe ethernet controllers via aliases on SOM
Add ethernet aliases to CC (Carrier card) description to create a
connection which is used by U-BOOT (fdt_fixup_ethernet()) for updating
local-mac-address in DT.
On Kria SOM MAC address is read from i2c eeprom at start and based on it
environment variables are created. Without creating aliases U-Boot is not
able to inject local-mac-address DT property and OS won't get the same MAC
address unless another i2c read is happening in OS.
Also aliases are using string not phandle (because of dtso) that's why full
path has to be provided but that shouldn't be a big issue because location
of ethernet controller is fixed.

arm64: zynqmp: Revert usb node drive strength and slew rate for zcu106
On a few zcu106 boards USB devices (Dell MS116 USB Optical Mouse, Dell USB
Entry Keyboard) are not enumerated on linux boot due to commit
'b8745e7eb488 ("arm64: zynqmp: Fix usb node drive strength and slew
rate")'.
To fix it as a workaround revert to working version and then investigate
at board level why drive strength from 12mA to 4mA and slew from fast to
slow is not working.

arm64: zynqmp: Fix pwm-fan polarity
The correct operating mode for the fan is inversed (1). The previous pwm
driver implementation had a bug and the polarity information was propagated
incorrectly to the kernel. The normal (0) polarity specified in the device
tree was incorrectly clearing the polarity bit in the counter control
register. After the bug fix, setting the polarity to inversed (1) in the
device tree will clear the polarity bit.
Also provide label for custom description based on this SOM.

arm64: zynqmp: Add thermal zones
Add some thermal trip points. We can't undervolt the CPUs to save power
when we underclock them, so there isn't really a point in throttling
them until we are about to overheat. As such, the passive trip point is
right below the critical trip point.
The critical trip point is the extended/industrial-grade maximum
junction temperature of 100C minus the maximum temperature sensor error
of 3.5C (in the range -55C to 110C). Automotive- and military-grade
parts can go up to 125C, but as far as I can tell there is no way to
detect them at runtime. Userspace can adjust the trip points at runtime,
but this may not be viable when booting above 100C. I think it's
reasonable to ask automotive/military users to edit their device trees
to bump the trip points, but if that proves to be an issue we can
always go with no default temperatures. However, that wouldn't be too
nice for the majority of extended/industrial users.
