[PATCH 073/459] drm/amdgpu/psp: add structure to support load toc in psp (v2)

[Alex Deucher]

From: Hawking Zhang <Hawking.Zhang at amd.com>

v2: rebase (Alex)

FIXME:
GFX_CMD_ID_PROG_REG     = 0x0000000B,   /* program regs */
GFX_CMD_ID_LOAD_TOC     = 0x0000000B,   /* Load TOC and obtain TMR size */
