usb: xhci: tegra: Add support for managing powergates
The Tegra XHCI controller requires that the XUSBA (for superspeed) and
XUSBC (for host) power-domains are enabled. Commit
8df127456f29
("soc/tegra: pmc: Enable XUSB partitions on boot") was added to force
on these power-domains if the XHCI driver is enabled while proper
power-domain support is added, to ensure the device did not hang on
boot. However, rather than forcing on these power-domains in the PMC
driver we can use the legacy Tegra powergate APIs to turn on these
power-domains during the probe of the Tegra XHCI driver.
In the near future we plan to move the Tegra XHCI driver to use the
generic PM domain framework for power-domains and so to prepare for
this only use the legacy Tegra powergate API if there is not PM
domain associated with device (ie. dev.pm_domain is NULL). Please
note that in the future the superspeed and host resets will be handled
by the generic PM domain provider and so these are only these are only
needed in the case where there is no generic PM domain.

The proposed patch adds compatibility quirks. Because the drive requires two
quirks (one to work with UAS, and another to work with usb-storage), adding this
under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS
receive the quirk. With the patch, the drive works reliably on UAS and usb-
storage.

usb: typec: wcove: Remove dependency on HW FSM
The USB Type-C PHY in Intel WhiskeyCove PMIC has build-in

Current way of having one array telling only the port speed,
and then two separate arrays with mmio addresses for usb2 and usb3 ports
requeres helper functions to transate hw to hcd, and hcd to hw port
numbers, and is hard to expand.
Instead create a structure describing a port, including the mmio address,
the port hardware index, hcd port index, and a pointer to the roothub
it belongs to.
Create one array containing all port structures in the same order the
hardware controller sees them. Then add an array of port pointers to
each xhci hub structure pointing to the ports that belonging to the
roothub.
This way we can easily convert hw indexed port events to usb core
hcd port numbers, and vice versa usb core hub hcd port numbers
to hw index and mmio address.
Other benefit is that we can easily find the parent hcd and xhci
structure of a port structure. This is useful in debugfs where
we can give one port structure pointer as parameter and get both
the correct mmio address and xhci lock needed to set some port
parameter.

usb: musb: remove references to default_a of struct usb_otg
musb drivers do not use the otg fsm framework, so referencing to
otg->default_a doesn't have any effect, so remove the references.
But tusb6010 glue driver uses it locally to control the vbus power, so
keep the references in tusb6010 only.
