The graphics driver is supposed to define the DIDL, which are used for
_DOD, not the BIOS. Restore that behaviour.

This is basically a revert of

commit 3143751f
Author: Zhang Rui <rui.zhang@intel.com>
Date:   Mon Mar 29 15:12:16 2010 +0800

    drm/i915: set DIDL using the ACPI video output device _ADR method return.

which went out of its way to cater to a specific BIOS, setting up DIDL
based on _ADR method. Perhaps that approach worked on that specific
machine, but on the machines I checked the _ADR method invents the
device identifiers out of thin air if DIDL has not been set. The source
for _ADR is also supposed to be the DIDL set by the driver, not the
other way around.

With this, we'll also limit the number of outputs to what the driver
actually has.

A side effect of this change is that the DIDL, and by proxy CADL, will
be initialized in the order of the connector list. That, in turn, has
internal panels in front, ensuring they're included in the DIDL and CADL
lists. Hopefully this ensures the BIOS does not block backlight hotkey
events, thinking the internal panel is off.

Support DRM out-fences by creating a sync_file with a fence for each CRTC
that sets the OUT_FENCE_PTR property.

We use the out_fence pointer received in the OUT_FENCE_PTR prop to send

The sync_file and fd are allocated/created before commit, but the
fd_install operation only happens after we know that commit succeed.

Decoupled MMIO is an alternative way to access forcewake domain
registers, which requires less cycles for a single read/write and
avoids frequent software forcewake.
This certainly gives advantage over the forcewake as this new
mechanism “decouples” CPU cycles and allow them to complete even
when GT is in a CPD (frequency change) or C6 state.

This can co-exist with forcewake and we will continue to use forcewake
as appropriate. E.g. 64-bit register writes to avoid writing 2 dwords
separately and land into funny situations.

v2:
- Moved platform check out of the function and got rid of duplicate
 functions to find out decoupled power domain (Chris)
- Added a check for forcewake already held and skipped decoupled
 access (Chris)
- Skipped writing 64 bit registers through decoupled MMIO (Chris)

v3:
- Improved commit message with more info on decoupled mmio (Tvrtko)
- Changed decoupled operation to enum and used u32 instead of
 uint_32 data type for register offset (Tvrtko)
- Moved HAS_DECOUPLED_MMIO to device info (Tvrtko)
- Added lookup table for converting fw_engine to pd_engine (Tvrtko)
- Improved __gen9_decoupled_read and __gen9_decoupled_write
 routines (Tvrtko)

v4:
- Fixed alignment and variable names (Chris)
- Write GEN9_DECOUPLED_REG0_DW1 register in just one go (Zhe Wang)

v5:
- Changed HAS_DECOUPLED_MMIO() argument name to dev_priv (Tvrtko)

There is now a new property called IN_FENCE_FD attached to every plane
state that receives sync_file fds from userspace via the atomic commit
IOCTL.

The fd is then translated to a fence (that may be a fence_array
subclass or just a normal fence) and then used by DRM to fence_wait() for
all fences in the sync_file to signal. So it only commits when all
framebuffers are ready to scanout.

v2: Comments by Daniel Vetter:
	- remove set state->fence = NULL in destroy phase
	- accept fence -1 as valid and just return 0
	- do not call fence_get() - sync_file_fences_get() already calls it
	- fence_put() if state->fence is already set, in case userspace
	set the property more than once.

Reference from drm_dp_aux description (about transfer):
Upon success, the implementation should return the number of payload bytes
that were transferred, or a negative error-code on failure. Helpers
propagate errors from the .transfer() function, with the exception of
the -EBUSY error, which causes a transaction to be retried. On a short,
helpers will return -EPROTO to make it simpler to check for failure.

The analogix_dp_transfer will return num_transferred, but if there is none
byte been transferred, the return value will be 0, which means success, we
should return error-code if transfer none byte.

for (retry = 0; retry < 32; retry++) {
	err = aux->transfer(aux, &msg);
