Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

We currently gate the update of the PMU state on the PMU being "ready".
The "ready" state is only set to true when the first vcpu run is
successful, and if it isn't, we never reach the update code.
So the "ready" state is never the right thing to check for, and it
should instead be the presence of the PMU feature, which makes
a bit more sense.

The ARMv8 architecture says that in the absence of FEAT_PMUv3,
all the PMU-related register generate an UNDEF. Let's make
sure that all our PMU handers catch this case by hooking into
check_pmu_access_disabled(), and add checks in a couple of
other places.
Note that we still cannot deliver an exception into the guest
as the offending cases are already caught by the RAZ/WI handling.
But this puts us one step away to architectural compliance.

We accept to configure a PMU when a vcpu is created, even if the
HW (or the host) doesn't support it. This results in failures
when attributes get set, which is a bit odd as we should have
failed the vcpu creation the first place.
Move the check to the point where we check the vcpu feature set,
and fail early if we cannot support a PMU. This further simplifies
the attribute handling.

When enabling the PMU in kvm_arm_pmu_v3_enable(), KVM returns early if the
PMU flag created is false and skips any other checks. Because PMU emulation
is gated only on the VCPU feature being set, this makes it possible for
userspace to get away with setting the VCPU feature but not doing any
initialization for the PMU. Fix it by returning an error when trying to run
the VCPU if the PMU hasn't been initialized correctly.
The PMU is marked as created only if the interrupt ID has been set when
using an in-kernel irqchip. This means the same check in
kvm_arm_pmu_v3_enable() is redundant, remove it.
