snd_timer_notify1() is called outside the spinlock and it retakes the
lock after the unlock. This is rather racy, and it's safer to move
snd_timer_notify() call inside the main spinlock.
The patch also contains a slight refactoring / cleanup of the code.
Now all start/stop/continue/pause look more symmetric and a bit better
readable.

Since the DWC USB2.0 host of Rockchip use dwc2 driver instead of
dwc_otg_310 driver, so delete these legacy hack code which contain
the old cru-soft-rst API directly.

We found the usb-phy lost devices detected ability after continuously
disconnect/connect, this patch add usb2-phy reset/deassert as one part
of previous workaround (commit c1ebf31) to fix it.

According to xHCI spec v1.1 section 6.4.5 TRB Completion Codes,
the standard XHCI controller provide a TRB Completion Status
'USB Transaction Error' to asserted in the case where the host
did not receive a valid response from the device, it's useful
to handle pending URBs on the endpoint when the USB device is
plugged out.
Unfortunately, some SOCs USB 3.0 modules lose the ability to
assert the 'USB Transaction Error' status when USB 3.0 device
disconnect. This may cause the pending URBs unhandled, even
lead to USB class driver stalled in waiting for URBs complete.
This patch flush pending URBs in usb_disable_device() when
USB 3.0 device disconnect, it will call xhci_urb_dequeue()
-> xhci_queue_stop_endpoint() to cancel pending URBs and
giveback URB status immediately.

Some special SoCs (e.g. rk322xh) USB3 PHY have problem to detect
disconnection, they lose the ability to detect an absence of Rx
termination specified in USB3 spec Table 6-21, fortunately, the
USB3 PHY can detect port link state change when USB3 device is
unplugged, so we can do soft disconnect according to the PLC.

The USB kerneldoc says that the actual_length field "is read in
non-iso completion functions", but the usbfs driver uses it for all
URB types in processcompl(). Since not all of the host controller
drivers set actual_length for isochronous URBs, programs using usbfs
with some host controllers don't work properly. For example, Minas
reports that a USB camera controlled by libusb doesn't work properly
with a dwc2 controller.
It doesn't seem worthwhile to change the HCDs and the documentation,
since the in-kernel USB class drivers evidently don't rely on
actual_length for isochronous transfers. The easiest solution is for
usbfs to calculate the actual_length value for itself, by adding up
the lengths of the individual packets in an isochronous transfer.

As the emmc is supplyed power by vcc_io, that's 3.3v voltage.
the default 1.8v volatge will cause the emmc error. as the following:
[ 17.096082 ] mmcblk1: error -115 sending stop command, original cmd
response 0x900, card status 0xb00
[ 17.127022 ] mmcblk1: error -110 transferring data, sector 664720, nr
72, cmd response 0x900, card status 0xb00
Remove the mmc-ddr-1_8v to keep the default the 3.3v voltage.
