drm/i915: Nuke intel_atomic_crtc_state_for_each_plane_state() from skl+ wm code

intel_atomic_crtc_state_for_each_plane_state() peeks at the
plane's current state without holding the plane's mutex, trusting
that the crtc's mutex will protect it. In practice that does work
since our planes can't move between pipes, but it sets a bad
example. intel_atomic_crtc_state_for_each_plane_state() also
relies on crtc_state.uapi.plane_mask which may be full of lies
when it comes to the bigjoiner stuff, so soon we can't use it as
is anyway. So best to just get rid of it entirely. Which we can
easily do by switching to the g4x/vlv "raw" watermark approach.

Later on we should even be able to move the "raw" watermark
computation into the normal .plane_check() code, leaving only
the merging/clamping of the final watermarks to the later
stages. But that will require adjusting the ilk+ wm code

  The fixes are for some reported issues in the interconnect and
  coresight drivers, nothing major.

  The "big" driver removal is the MIC drivers have been asked to be
  removed as the hardware never shipped and Intel no longer wants to
  maintain something that no one can use. This is welcomed by many as
  the DMA usage of these drivers was "interesting" and the security
  people were starting to question some issues that were starting to be
  found in the codebase.

  Note, one of the subsystems for this driver, the "VOP" code, will
  probably come back in future kernel versions as it was looking to
  potentially solve some PCIe virtualization issues that a number of
  other vendors were wanting to solve. But as-is, this codebase didn't
  work for anyone else so no actual functionality is being removed.

IRQs disabled and can't get migrated, so if we get migrated both CPUs
must have 0 and it doesn't matter which 0 we read.

And while that is true; it isn't the whole store, on pretty much all
architectures (except x86) this can result in computing the address for
one CPU, getting migrated, the old CPU continuing execution with another
task (possibly setting recursion) and then the new CPU reading the value
of the old CPU, which is no longer 0.

KVM: arm64: Handle Asymmetric AArch32 systems

On a system without uniform support for AArch32 at EL0, it is possible
for the guest to force run AArch32 at EL0 and potentially cause an
illegal exception if running on a core without AArch32. Add an extra
check so that if we catch the guest doing that, then we prevent it from
running again by resetting vcpu->arch.target and return
ARM_EXCEPTION_IL.

We try to catch this misbehaviour as early as possible and not rely on
an illegal exception occuring to signal the problem. Attempting to run a
32bit app in the guest will produce an error from QEMU if the guest
exits while running in AArch32 EL0.

Tested on Juno by instrumenting the host to fake asym aarch32 and
instrumenting KVM to make the asymmetry visible to the guest.

drm/i915: Parametrize BXT_DE_PORT_HP_DDI with hpd_pin

Use hpd_pin to parametrize BXT_DE_PORT_HP_DDI() to make it clear
these have nothing to do with DDI ports or PHYs as such. The only
thing that matters is the HPD pin assignment.

and add a comment to explain the situation.
