This is an important part of the DDI initalization as well as
for changing the voltage during DisplayPort link training.
This new sequence for Cannonlake is more like Broxton style
but still with different registers, different table and
different steps.
v2: Do not write to DW4_GRP to avoid overwrite individual loadgen.
Fix PORT_CL_DW5 SUS Clock Config set.
v3: As previous platforms use only eDP table if low voltage was
requested.
v4: fix Werror:maybe uninitialized (Paulo)
v5: Rebase on top of dw2_swing_sel changes
on previous patches.

These tables are used on voltage wswing sequence initialization
on Cannonlake.
It is a complete new format now in use by the voltage swing team,
not following any other standard in use by any other platform.
Also the registers are different as well. So let's redefine
the translation table for Cannonlake.
The table is huge. So we minimized with the fields that are
different or might be different anytime soon. The common
values will be hardcoded on the voltage swing sequence.
v2: Merge the lower and the upper bits to match the spec table
and make review easier. This was possible with the good
idea for Manasi with a better way to handle it on the bit
macro definition presented on previous patch.

Although CNL follows PLL initialization more like Skylake
than Broxton we have a completely different initialization
sequence and registers used.
One big difference from SKL is that CDCLK PLL is now
exclusive (ADPLL) and for DDIs and MIPI we need to use
DFGPLLs 0, 1 or 2.
v2: Accept all Ander's suggestions and fixes:
- Registers and bits names prefix
- Group pll functions
- bits masks fixes
- remove read and modify on cfgcr1
- fix cfgcr0 setup
v3: Set SSC_ENABLE for DP.
Fix HDMI_MODE cfgcr0.
Avoid touch cfgcr0 on DP.
Add missed else on dpll_mgr definition so we use cnl one, not hsw.
v3: Centra freq should be always set to default and change bits

One of the steps for PLL (un)initialization is to (un)map
the correspondent DDI that is actually using that PLL.
So, let's do this step following the places already stablished
and used so far, although spec put this as part of PLL
initialization sequences.
v2: Use proper prefix on bits names as suggested by Ander.
v3: Add missed "~". Without that the logic was inverted
so we were disabling interrupts.

similar to BXT, but there are some annoying differences which means
trying to share more code might not be feasible:
* PLL ratio now lives in the PLL enable register
* pcode came from SKL, not from BXT
We support three cdclk frequencies: 168,336,528 Mhz. The first two
use the same PLL frequency, the last one uses a different one meaning
we once again may need to toggle the PLL off and on when changing
cdclk.

Commit abb2ea7dfd ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.
So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.
Maybe this makes clang happier.

This is triggered by running both win7 and win2016 on L1 KVM simultaneously,
and then gives stress to memory on L1, I can observed this hang on L1 when
at least ~70% swap area is occupied on L0.
This is due to async pf was injected to L2 which should be injected to L1,
L2 guest starts receiving pagefault w/ bogus %cr2(apf token from the host
actually), and L1 guest starts accumulating tasks stuck in D state in
kvm_async_pf_task_wait() since missing PAGE_READY async_pfs.
This patch fixes the hang by doing async pf when executing L1 guest.
