drm/amdkfd: Update context save handling for multi XCC setup (v2)

Context save handling needs to be updated for a multi XCC
setup:
- On a multi XCC setup, KFD needs to report context save base
address and size for each XCC in MQD.
- Thunk will allocate a large context save area covering all
XCCs which will be equal to: num_of_xccs in a partition * size
of context save area for 1 XCC. However, it will report only the
size of context save area for 1 XCC only in the ioctl call.
- Driver then setups the MQD correctly using the size passed from
Thunk and information about number of XCCs in a partition.
- Update get_wave_state function to return context save area
for all XCCs in the partition.

v2: update the get_wave_state function for mqd manager v11 (Morris)

drm/amdkfd: Introduce kfd_node struct (v5)

Introduce a new structure, kfd_node, which will now represent
a compute node. kfd_node is carved out of kfd_dev structure.
kfd_dev struct now will become the parent of kfd_node, and will
store common resources such as doorbells, GTT sub-alloctor etc.
kfd_node struct will store all resources specific to a compute
node, such as device queue manager, interrupt handling etc.

This is the first step in adding compute partition support in KFD.

v2: introduce kfd_node struct to gc v11 (Hawking)
v3: make reference to kfd_dev struct through kfd_node (Morris)
v4: use kfd_node instead for kfd isr/mqd functions (Morris)

drm/amdkfd: Add an optional argument into update queue operation(v2)

Currently, queue is updated with data in queue_properties.
And all allocated resource in queue_properties will not
be freed until the queue is destroyed.

But some properties(e.g., cu mask) bring some memory
management headaches(e.g., memory leak) and make code
complex. Actually they have been copied to mqd and
don't have to persist in queue_properties.

Add an argument into update queue to pass such properties,
then we can remove them from queue_properties.

v2: Don't use void *.

drm/amdkfd: Account for SH/SE count when setting up cu masks.

On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and
lower 16 bits. We need to detect this and apply cu masking to each
SH. The cu mask bits are assigned first to each SE, then to
alternate SHs, then finally to higher CU id. This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.

v2: Use max SH/SE rather than max SH in cu_per_sh.

v3: Fix comment blocks, ensure se_mask is initially zero filled,
and correctly assign se.sh.cu positions to unset bits in cu_mask.

The mqd_manager module handles MQD data structures.
MQD stands for Memory Queue Descriptor, which is used by the H/W to

v3:

Removed new typedefs
Removed pragma pack 4
Remove cik_mqds.h file
Changed lower_32/upper_32 calls to use linux macros
Used new gart allocation functions
Added documentation

v4:

Added missing initialization of the addr field in init_mqd()

Setting the hqd persistent.preload_req bit ON so that when queues switches
on/off, their context will kept and read from the mqd when the cp reassign
them, and thus the dispatched workload context kept consistent without any
interrupts.
