63edf1b469 drm/amd/powerplay: Delete an unnecessary variable initialisation in phm_dispatch_table()

Thus omit the explicit initialisation at the beginning.

eb923ea6fa drm/amd/powerplay: Change assignment for a buffer variable in phm_dispatch_table() v2 
The variable "temp_storage" was eventually reassigned with a pointer.
Thus omit the explicit initialisation at the beginning.

v2: agd: fix coding style
