KVM fixes for 6.14 part 1

- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being emulated
by KVM to fix a NULL pointer dereference.

- Enter guest mode (L2) from KVM's perspective before initializing the vCPU's
nested NPT MMU so that the MMU is properly tagged for L2, not L1.

- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as the
guest's value may be stale if a VM-Exit is handled in the fastpath.

accel/amdxdna: Add MODULE_FIRMWARE() declarations

Initramfs building tools such as dracut will look for a MODULE_FIRMWARE()
declaration to determine which firmware to include in the initramfs
when a driver is included in the initramfs.

As amdxdna doesn't declare any firmware this causes the driver to fail
to load with -ENOENT when in the initramfs. Add the missing declaration
for possible firmware.

accel/amdxdna: Enhance power management settings

Add SET_STATE ioctl to configure device power mode for aie2 device.
Three modes are supported initially.

POWER_MODE_DEFAULT: Enable clock gating and set DPM (Dynamic Power
Management) level to value which has been set by resource solver or
maximum DPM level the device supports.

POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPM
level the device supports.

POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPM
level the device supports.

Disabling clock gating means all clocks always run on full speed. And
the different clock frequency are used based on DPM level been set.
Initially, the driver set the power mode to default mode.
