If dynamic dptx power domain ctrl is enabled and dptx power
domain not enabled when init dptx controller, the dptx power
domain will be disabled though the uboot logo is enable. this
will cause display issue. To avoid this issue, it need enable
dptx power domain when enable uboot logo.

1. Select the usb2 phy interrupt logic clock from OSC clock
to support interrupt detection if VD_LOGIC is powerdown.
2. Set the linestate filter time control register depends
on the OSC 24MHz clock during suspend.

When the ISR is blocked, it's possible that the original job has already
been released while the scheduler is now running a new job. Therefore,
it is necessary to check whether the current job has already triggered a
hardware interrupt.

We may want to know how many size of a gem object is allocated, but
this size in rockchip_gem_object for no-IOMMU devices will not be set.
There are two ways to use rockchip GEMs, one is to create GEMs via DRM,
and the other is to import buffer created by other devices via DMA-BUF
and map it. For no-IOMMU devices, neither of them will set the buffer
size.
Let's set the size in rockchip_gem_object when we create a new rockchip
gem.

(cherry picked from commit 4ea4d4808e342ddf89ba24b93ffa2057005aaced)
The RK3576 platform doesn't use the dwc3 glue layer
which supports to call dwc3_of_simple_shutdown and
dwc3_remove on system shutdown. Therefore, the RK3576
dwc3 controller still keeps working on system shutdown,
and it may cause pending usb irq if usb transmission
happens when do reboot test.
This patch adds shutdown support for RK3576 platform.

Test on RK3576 EVB1, if do tcpci_unregister_port on
husb311_shutdown, it will cause two issues in reboot
test.
1. Introducing unnecessary usb mode initialization
in dwc3 driver, the call trace:
husb311_shutdown -> tcpci_unregister_port -> tcpm_reset_port ->
tcpm_mux_set -> usb_role_switch_set_role -> dwc3_usb_role_switch_set
2. More seriously, if the dwc3 driver is unbind before
husb311_shutdown, it will cause kernel panic.
(1) echo 23000000.usb > /sys/bus/platform/drivers/dwc3/unbind
(2) do reboot
(3) kernel panic with the following log:

2. Disable disconnect rise and disconnect fall irq. Because these
two interrupts will be triggered immediately after the system goes
