Some PC USB Hosts (e.g Dell laptop) fail to send
SetInterface(AltSet=0) to stop capture/playback
when PC enter suspend or play YouTube Video.
To be compatible with these PC, add this patch to
stop capture/playback prior to start again if the
stream_state is true.

This patch add uevent to notify the application layer when it should
playback or capture and setting the accuration sample rate.
The event consists of three parts, namely USB_STATE, STREAM_DIRECTION
and STREAM_STATE. For example:
g_audio_work: sent uac uevent USB_STATE=SET_INTERFACE STREAM_DIRECTION=IN STREAM_STATE=OFF
g_audio_work: sent uac uevent USB_STATE=SET_INTERFACE STREAM_DIRECTION=OUT STREAM_STATE=ON
g_audio_work: sent uac uevent USB_STATE=SET_SAMPLE_RATE STREAM_DIRECTION=OUT SAMPLE_RATE=44100

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.

For integrated PHY, there is no stmmac_mdio_reset(), so add callback for
the PHY power control during ethernet interface up/down, and suspend/resume.

When call pm_runtime_get_sync(), the runtime callback will change clock
source to normal pll, but now pm_runtime_get_sync() is called in a delay
work and the wakelock seems to be invalid on linux system,
so when suspend the pm_runtime_get_sync() may not be called.

Powergood integrated on npor is an interrupt signal that triggers
an interrupt when a specific level value is detected.
Do some software protection for the system when the interrupt is
triggered.
