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.

accel/amdxdna: Add error handling

When there is a hardware error, the NPU firmware notifies the host through
a mailbox message. The message includes details of the error, such as the
tile and column indexes where the error occurred.

The driver starts a thread to handle the NPU error message. The thread
stops the clients which are using the column where error occurred. Then
the driver resets that column.

accel/amdxdna: Add GEM buffer object management

There different types of BOs are supported:

- shmem
A user application uses shmem BOs as input/output for its workload running
on NPU.

- device memory heap
The fixed size buffer dedicated to the device.

- device buffer
The buffer object allocated from device memory heap.

- command buffer
The buffer object created for delivering commands. The command buffer
object is small and pinned on creation.

New IOCTLs are added: CREATE_BO, GET_BO_INFO, SYNC_BO. SYNC_BO is used
to explicitly flush CPU cache for BO memory.

accel/amdxdna: Add hardware context

The hardware can be shared among multiple user applications. The
hardware resources are allocated/freed based on the request from
user application via driver IOCTLs.

DRM_IOCTL_AMDXDNA_CREATE_HWCTX
Allocate tile columns and create a hardware context structure to track the
usage and status of the resources. A hardware context ID is returned for
XDNA command execution.

DRM_IOCTL_AMDXDNA_DESTROY_HWCTX
Release hardware context based on its ID. The tile columns belong to
this hardware context will be reclaimed.

DRM_IOCTL_AMDXDNA_CONFIG_HWCTX
Config hardware context. Bind the hardware context to the required
resources.

Initially, a management mailbox channel is up and running. The driver may
request firmware to create/destroy more channels dynamically through

Add driver internal mailbox interfaces.
- create/destroy a mailbox channel instance
- send a message to the firmware through a specific channel
- wait for a notification from the specific channel
