amdgpu_device_resume() & amdgpu_device_init() have a high
time consuming call of amdgpu_late_init() which sets the
clock_gating state of all IP blocks and is blocking.
This patch defers only this setting of clock gating state
operation to post resume of amdgpu driver but ideally before
the UI comes up or in some cases post ui as well.

With this change the resume time of amdgpu_device comes down
from 1.299s to 0.199s which further helps in reducing the overall
system resume time.

V1: made the optimization applicable during driver load as well.

TEST:(For ChromiumOS on STONEY only)
* UI comes up
* amdgpu_late_init() call gets called consistently and no errors reported.

The current code here is really, really bad. A huge amount of it looks
to be copy pasted, it has some weird hatred of arrays and code sharing,
switch cases everywhere for things that really don't need them, and it
makes the file seem immensely more complex then it actually is. This is
a pain for maintanence, and is vulnerable to more weird irq handling
bugs.

So, let's start cleaning this up a bit. Modify all of the IRQ handlers
for evergreen/si so that they just use for loops. As well, we add a
helper function radeon_irq_kms_set_irq_n_enabled(), whose purpose is
just to update the state of registers that enable/disable interrupts
while printing any changes to the set of enabled interrupts to the
kernel log.

Note in this commit, since vblank/vline irq acking is intertwined with
page flip irq acking, we can't cut out all of the copy paste in
evergreen/si_irq_ack() just yet.

KIQ is the Kernel Interface Queue for managing the MEC.  Rather than setting
up rings via direct MMIO of ring registers, the rings are configured via
special packets sent to the KIQ.  The allows the MEC to better manage shared
resources and certain power events. It also reduces the code paths in the
driver to support and is required for MEC powergating.
