[PATCH 2/2] drm/amdgpu: remove memory training p2c buffer reservation(V2)
From: "Tianci.Yin"
IP discovery TMR(occupied the top VRAM with size DISCOVERY_TMR_SIZE)
has been reserved, and the p2c buffer is in the range of this TMR, so
the p2c buffer reservation is unnecessary.

Hi Guchun,
Thanks very much for your suggestion.
I will refine it and send it out later.

[Guchun] If we have to remove such buffer reservation, from coding style's
perspective, I suggest removing error handler code by "goto" too in
amdgpu_ttm_training_reserve_vram_init.
After removing p2c buffer reservation from this function, there is only one
buffer reservation case for c2p. So direct error handle and return should be
better.
