A100 features an updated DPHY, which moves PLL control inside the DPHY
register space (previously the PLL was controlled from the CCU). It also
requires a modified analog power-on sequence. This "combo PHY" can also
be used as an LVDS PHY, but that is not yet supported by the driver.

The A100 variant uses the same values for the timing registers, and it
uses the same final power-on sequence, but it needs a different analog
register configuration in the middle. Support this by moving the
variant-specific parts to a hook provided by the variant.

The A100 variant of the DPHY requires configuring the analog registers
before setting the global enable bit. Since this order also works on the
other variants, always use it, to minimize the differences between them.

While all variants of the DPHY likely support RX mode, the new variant
in the A100 is not used in this direction by the BSP, and it has some
analog register changes, so its RX power-on sequence is unknown. To be
safe, limit RX support to variants where the power-on sequence is known.

Note that the binding does not try to describe every register subregion
and instead the driver holds the corresponding offsets.

The DP_PHY registers have erroneously been referred to as "PCS"
registers since DisplayPort support was added to the QMP drivers
(including in the devicetree binding).
Rename the corresponding pointer to match the register names.
Note that the repeated "dp" in the field name is intentional and this DP
register block is called "DP_PHY" (not just "PHY").

Move the device-id table after probe() and next to the driver structure
to keep the driver callback functions grouped together.

Commit 52e013d0bffa ("phy: qcom-qmp: Add support for DP in USB3+DP combo
phy") added support for the DisplayPort part of QMP PHYs but
unfortunately did so by duplicating parts of the shared configuration,
something which has lead to subtle bugs depending on probe order.
As the resources have always been requested based on the USB
configuration, make sure to not rely on fields from the DP configuration
when using them (e.g. in case they get out of sync) and remove the now
unused fields from the DP configurations.

Drop the confused runtime-suspend type check which effectively broke
runtime PM if the DP child node happens to be parsed before the USB
child node during probe (e.g. due to order of child nodes in the
devicetree).
Instead use the new driver data USB PHY pointer to access the USB
configuration and resources.

The PHY is powered on during phy-init by setting the SW_PWRDN bit in the
COM_POWER_DOWN_CTRL register and then setting the same bit in the in the
PCS_POWER_DOWN_CONTROL register that belongs to the USB part of the
PHY.
Currently, whether power on succeeds depends on probe order and having
the USB part of the PHY be initialised first. In case the DP part of the
PHY is instead initialised first, the intended power on of the USB block
results in a corrupted DP_PHY register (e.g. DP_PHY_AUX_CFG8).
Add a pointer to the USB part of the PHY to the driver data and use that
to power on the PHY also if the DP part of the PHY is initialised first.

The SC8180X has two resets but the DP configuration erroneously
described only one.
In case the DP part of the PHY is initialised before the USB part (e.g.
depending on probe order), then only the first reset would be asserted.

Add a dedicated configuration for SDM845 rather than reuse the
