Problem:
During GPU reset we call the GPU scheduler to suspend it's
thread, those two functions in amdgpu also suspend and resume
the sceduler for their needs but this can collide with GPU
reset in progress and accidently restart a suspended thread
before time.
Fix:
Serialize with GPU reset.

Some RCGs (the gfx_3d_src_clk in msm8998 for example) are basically just
some constant ratio from the input across the entire frequency range. It
would be great if we could specify the frequency table as a single entry
constant ratio instead of a long list, ie:
{ .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 },
{ }
So, lets support that.
We need to fix a corner case in qcom_find_freq() where if the freq table
is non-null, but has no frequencies, we end up returning an "entry" before
the table array, which is bad. Then, we need ignore the freq from the
table, and instead base everything on the requested freq.

When MSM8998 support was added, and analysis was done to determine what
clocks would be consumed. That analysis had a flaw, which caused the
pnoc to be skipped. The pnoc clock needs to be on to access the uart
for the console. The clock is on from boot, but has no consumer votes
in the RPM. When we attempt to boot the modem, it causes the RPM to
turn off pnoc, which kills our access to the console and causes CPU hangs.
We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in
an implicit vote for linux and prevent issues when booting modem.
Hopefully pnoc can be consumed by the interconnect framework in future
so that Linux can rely on explicit votes.

Rework SCHED API to allow offloading TC-MQPRIO QoS configuration.
The existing QUEUE based rate limiting throttles all queues sharing
a traffic class, to the specified max rate limit value. So, if
multiple queues share a traffic class, then all the queues get
the aggregate specified max rate limit.
So, introduce the new FLOWC based rate limiting, where multiple
queues can share a traffic class with each queue getting its own
individual specified max rate limit.
For example, if 2 queues are bound to class 0, which is rate limited
to 1 Gbps, then 2 queues using QUEUE based rate limiting, get the
aggregate output of 1 Gbps only. In FLOWC based rate limiting, each
queue gets its own output of max 1 Gbps each; i.e. 2 queues * 1 Gbps
rate limit = 2 Gbps.
