Include the MediaTek TPHY in a power domain. Add the 'power-domains'
property in the Device Tree (DT) Schema and set 'maxItems: 1'.
Also, include a reminder in the description of the 'power-domains'
property.

Due to some old SoCs with shared t-phy between usb3 and pcie only support
force-mode switch, and shared and non-shared t-phy may exist at the same
time on a SoC, can't use compatible to distinguish between shared and
non-shared t-phy, add a property to supported it.
Currently, only support switch from default pcie mode to usb3 mode.
But now prefer to use "mediatek,syscon-type" on new SoC as far as possible.

The pattern for the nodename only allows t-phy@... , however, for the case
when the t-phy has no `reg` and only `ranges` (basically when the t-phy
is just a parent node), dtc will throw this warning:
Warning (unit_address_vs_reg): /t-phy@1a243000: node has a unit name, but no reg or ranges property
For a node like this:
sata_phy: t-phy@1a243000 {
ranges;
sata_port: sata-phy@1a243000 {
reg = <0 0x1a243000 0 0x0100>;
};
};
it is normal that the parent node 't-phy' would be without any address, as in:
sata_phy: t-phy {
ranges;
sata_port: sata-phy@1a243000 {
reg = <0 0x1a243000 0 0x0100>;
};
};
because being just a holder it does not have its own reg.
However the binding does not allow such a name for the t-phy, so with this
patch, making the `@[0-9a-f]+` part optional, such node is possible.

The PHYA architecture is updated, and doesn't support slew rate
calibration anymore on 7nm or advanced process, add a new version
number to support it.
Due to the FreqMeter bank is not used but reserved, it's backward
with v2 until now.
For mt8195, no function changes when use generic v2 or v3 compatible,
but prefer to use v3's compatible, it will not waste the time to
calibrate the slew rate, and also correspond with hardware version.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.
