[ Upstream commit 6616b5e1999146b1304abe78232af810080c67e3 ]

In 'struct phm_ppm_table *ptr' allocation using kzalloc, an incorrect
structure type is passed to sizeof() in kzalloc, larger structure types
were used, thus using correct type 'struct phm_ppm_table' fixes the
below:

drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/process_pptables_v1_0.c:203 get_platform_power_management_table() warn: struct type mismatch 'phm_ppm_table vs _ATOM_Tonga_PPM_Table'
