[why]
According to DP specs, in EQ DONE phase of link training, we
should lower lane count when at least one CR DONE bit is set to 1, while
lower link rate when all CR DONE bits are 0s. However in our code, we will
treat both cases as latter. This is not exactly correct based on the specs
expectation.
[how]
Check lane0 CR DONE bit when it is still set but CR DONE fails,
we treat it as a partial CR DONE failure in EQ DONE phase, we
will follow the same fallback flow as when ED DONE fails in EQ
DONE phase.

Add a new KFD ioctl to return the largest possible memory size that
can be allocated as a buffer object using
kfd_ioctl_alloc_memory_of_gpu. It attempts to use exactly the same
accept/reject criteria as that function so that allocating a new
buffer object of the size returned by this new ioctl is guaranteed to
succeed, barring races with other allocating tasks.
This IOCTL will be used by libhsakmt:

[Why]
There is a theoretical problem in prior patches for reducing the stack
size of *update_bw_bounding_box() functions.
By modifying the soc.clock_limits[n] struct directly, this can cause
unintended behavior as the for loop attempts to swap rows in
clock_limits[n]. A temporary struct is still required to make sure we
stay functinoally equivalent.
[How]
Add a temporary clock_limits table to the SOC struct, and use it when
swapping rows.

[Why&How]
There are cases where swizzle modes are set but modifiers arent. For
such a userspace, we need not check modifiers while checking
compatibilty in the drm hook for checking plane format.
Ignore checking modifiers but check the DCN generation for the
supported swizzle mode.
