44d6e160f6 drm/amd/pm: setup APU dpm clock table in SMU HW initialization 
As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()
where current APU dpm clock table setup is performed. So, NULL
pointer dereference will be triggered. By moving APU dpm clock
table setup to smu_hw_init(), this can be avoided.

bae82e8418 drm/amd/pm: Replace one-element array with flexible-array in struct phm_ppt_v1_pcie_table

a dynamically sized set of trailing elements in a structure. Kernel code

Refactor the code according to the use of a flexible-array member in

the struct_size() helper to calculate the size for the allocation.

0e319cfeb3 drm/amd/pm: Replace one-element array with flexible-array in struct phm_acp_clock_voltage_dependency_table 
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

Refactor the code according to the use of a flexible-array member in
struct phm_acp_clock_voltage_dependency_table, instead of a one-element
array, and use the struct_size() helper to calculate the size for the
allocation.

Also, save some heap space as the original code is multiplying
table->numEntries by sizeof(struct phm_acp_clock_voltage_dependency_table)
when it should have multiplied it by sizeof(phm_acp_clock_voltage_dependency_record)
instead.

d74a09c8af drm/amdgpu/swsmu: fix ARC build errors 
We want to use the dev_* functions here rather than the pr_* variants.
Switch to using dev_warn() which mirrors what we do on other asics.

Fixes the following build errors on ARC:

../drivers/gpu/drm/amd/amdgpu/../powerplay/navi10_ppt.c: In function 'navi10_fill_i2c_req':
../arch/arc/include/asm/bug.h:24:2: error: implicit declaration of function 'pr_warn'; did you mean 'drm_warn'? [-Werror=implicit-function-declaration]

../drivers/gpu/drm/amd/amdgpu/../powerplay/sienna_cichlid_ppt.c: In function 'sienna_cichlid_fill_i2c_req':
../arch/arc/include/asm/bug.h:24:2: error: implicit declaration of function 'pr_warn'; did you mean 'drm_warn'? [-Werror=implicit-function-declaration]
