tips:
1. If fd has imported, then just copy mem_regiony struct.
2. Task is the unit for running, and mem_region is the
internal element of task.
3. In mem_regions, it can only kref_get once with the same fd,
instead of all fds which the same fd.

The cpll clk gate bits had an ordering issue. This led to the loss of
the boot sdmmc controller when the gmac was shut down with:
`ip link set eth0 down`
as the cpll_100m was shut off instead of the cpll_62p5.
cpll_62p5, cpll_50m, cpll_25m were all off by one with cpll_100m
misplaced.

According to USB Audio Device 1.0 Spec, Ch4.6.1.1:
The wMaxPacketSize of endpoint is defined as follows:
Maximum packet size of endpoint is capable of sending
or receiving when this configuration is selected. This
is determined by the audio bandwidth constraints of
the endpoint.
In current code, the wMaxPacketSize is limited to 200,
and the bInterval is set to 4 (1ms). That is, the maximum
bandwidth over USB bus is 200 * 1000 = 200000 bytes.
We find an issue about bandwidth limitation when we try to
support UAC1 with 8ch * 16bit * 16KHz on RK3308 platform,
which needs more bandwidth than it can support.
This patch sets the wMaxPacketSize dynamically according
to the parameters of UAC1. It is similar to the same thing
done earlier for f_uac2.

As per UAC2 Audio Data Formats spec (2.3.1.1 USB Packets),
if the sampling rate is a constant, the allowable variation
of number of audio slots per virtual frame is +/- 1 audio slot.
It means that endpoint should be able to accept/send +1 audio
slot.
Previous endpoint max_packet_size calculation code
was adding sometimes +1 audio slot due to DIV_ROUND_UP
behaviour which was rounding up to closest integer.
However this doesn't work if the numbers are divisible.
It had no any impact with Linux hosts which ignore
this issue, but in case of more strict Windows it
caused rejected enumeration
Thus always add +1 audio slot to endpoint's max packet size

I test on RK3399 IND EVB running Android R system, and
set the USB gadget as UVC function via configfs, both
the USB 2.0 and 3.0 UVC have preview abnormal problems.
If the CPU enter deeper sleep, the USB DMA transfer gets
corrupted, and the UVC ISOC transmission lost data.
This patch puts in a "pm_qos_latency" requirement which
will keep the CPU out of the deeper sleep states when
UVC stream on. And allow the CPU to enter deeper sleep
state after UVC stream off.
