[ Upstream commit 706feb26f890e1b8297b5d14975160de361edf4f ]

fix other navi asic set peak performance level error.
because the navi10_ppt.c will handle navi12 14 asic,
it will use navi10 peak value to set other asic, it is not correct.

after patch:
only navi10 use custom peak value, other asic will used default value.
