This commit adds sleepwalk/wake and suspend/resume interfaces
to Tegra XUSB PHY driver.
Tegra XUSB host controller driver makes use of sleepwalk functions
to enable/disable sleepwalk circuit which is in always-on partition
and can respond to USB resume signals when controller is not powered.
Sleepwalk can be enabled/disabled for any USB UPHY individually.
- tegra_xusb_padctl_enable_phy_sleepwalk()
- tegra_xusb_padctl_disable_phy_sleepwalk()
Tegra XUSB host controller driver makes use of wake functions to
enable/disable/query wake circuit which is in always-on partition
can wake system up when USB resume happens.
Wake circuit can be enabled/disabled for any USB PHY individually.
- tegra_xusb_padctl_enable_phy_wake()
- tegra_xusb_padctl_disable_phy_wake()
- tegra_xusb_padctl_remote_wake_detected()
This commit also adds two system suspend stubs that can be used to
save and restore XUSB PADCTL context during system suspend and
resume.
- tegra_xusb_padctl_suspend_noirq()
- tegra_xusb_padctl_resume_noirq()

Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs.
This hardware block used to be exposed as a pin controller, but it turns
out that this isn't a good fit. The new driver and DT binding much more
accurately describe the hardware and are more flexible in supporting new
SoC generations.
