If the hdmi is plug out during the kernel logo phase and
hwc is not initialized, the hpd event cannot be received,
hdmi will not be disabled. Even if the hdmi is plugged in,
it will not actually be reinitialized, resulting in no signal output.
In this status, kernel must set mode_changed flag to true that
disable/enable hdmi when hwc enable hdmi.

When the frequency before and after color switching is the
same, the resolution switching process is not performed.
Instead, go through the following process:
connector atomic check--->set avmute--->config hdmi controller
-->config vop-->connector atomic commit-->clear avmute.
This way the HDMI output will not be interrupted, the black
screen time will be shorter, and the user experience will be
better.

RK3528 hdmi hpd 5v io is always being pulled down.
This workaround is set hpd 5v io to gpio function and
receive hpd signal from sink.
When hpd status is changed, gpio interrupt will trigger,
then set the hdmi_snk_det reg to change the hpd status of
the hdmi controller. Finally trigger the hpd interrupt
of the hdmi controller.

The xHCI specification 1.1 does not require xHCI-compliant
controllers to always enable hardware USB2 LPM. However,
the current xHCI driver always enable it when seeing HLC=1.
On rv1106 platforms, the xHCI USB2 LPM is enabled by default.
And we found that a lot of USB Disks have USB2 HW LPM broken
issue when connected to rv1106 USB2 OTG interface.
Here are a part of special USB Disks with USB2 HW LPM broken:
1. idVendor=325d, idProduct=6410, Manufacturer: aigo
2. idVendor=21c4, idProduct=0cd1, Manufacturer: Lexar
3. idVendor=0951, idProduct=1666, Manufacturer: Kingston
When use dd command to write to these USB Disks, it may fail
with the following log:
[ 2844.700148] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
[ 2889.072272] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
[ 2921.498045] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
......
[ 2953.923773] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
Theoretically, we can add USB_QUIRK_NO_LPM individually for
these special USB Disks, however, it's difficult to cover all
USB Disks. So it's better to disable the USB2 LPM for xHCI
on rv1126 platforms.
