In some case, the hpd is detected but the aux is not ready. It's
better to detect aux status before get link info from dpcd.
When the dptx send a aux request transaction, the dptx's max
aux timeout value is 3.2 ms, set the timeout value as 10ms
is enough.

ALSA core blocks userspace for 10 seconds for PCM R/W default.
Consider the situation BT-slave which acts as SLAVE mode, when
BT-master offline sometime, the CLK lost, user have to wait the
core timeout(10s), it's quite bad experience.
This patch allows userspace to override the WAIT_TIME to recover
more quickly from terminal audio stream. especially for stream
which have no mechanism to detect the LINK offline.
Usage:
/# amixer -c 0 contents | grep Wait
numid=43,iface=PCM,name='PCM Read Wait Time MS'
numid=44,iface=PCM,name='PCM Write Wait Time MS'
/# amixer -c 0 cset numid=43 500
numid=43,iface=PCM,name='PCM Read Wait Time MS'
; type=INTEGER,access=rw------,values=1,min=0,max=10000,step=1
: values=500

After FS idle, should wait at least 2 BCLK cycle to make sure
the CLK gate operation done, and then disable mclk.
Otherwise, the BCLK is still ungated. once the mclk is enabled,
there maybe a risk that a few BCLK cycle leak. especially for
low speed situation, such as 8k samplerate.
The best way is to use delay per samplerate, but, the max time
is quite a tiny value, so, let's make it simple to use the max
time. the max BCLK cycle time is: 31us @ 8K-8Bit (64K BCLK)
udelay(40);
Should wait for one BCLK ready after DIV and then ungate clk to
achieve the clean clk. the max BCLK cycle time is:
15.6us @ 8K-8Bit (64K BCLK)
udelay(20);
Increase the max timeout to 1ms to fix FS idle failed. because
it's not enough for 8k samplerate.

This patch add support for keeping BCLK / FSYNC always on.
it's required by some devices, such as HDMI, PA, etc.
For example: on HDMI situation
There are some TVs require maintaining N/CTS packets or AUDS
packets to keep audio logic active, otherwise, the first tone
may be lost.
In order to optimize the user experience, we need to ensure
continuous transmission of N/CTS and AUDS packets from the
HDMI-TX, so that the SINK TV devices can maintain audio logic
activation, promptly process audio data, and achieve the
completeness of the first tone.
We init a 48k I2S-STANDARD clock timing as default.

There is a issue of stuck during dual-core collabration,
and the hw timeout count will be blocked by default,
and only soft timeout can be triggered to exit.
However, the soft timeout is too loog, so config reg to not mask the hw
timeout.

In some platform, can not do pmu_idle_request before cru reset.
Resetting without pmu_idle_request while the hw is running
will result in a bus err.
So stop hw first before cru reset to prevent the issue.
