drm/amd/display: fix replay_mode kernel-doc warning

Fix the typo in the kernel-doc for @replay_mode to prevent
kernel-doc warnings:

drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h:623: warning: Incorrect use of kernel-doc format:          * @replay mode: Replay supported
drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h:626: warning: Function parameter or member 'replay_mode' not described in 'amdgpu_hdmi_vsdb_info'

Fixes: ec8e59c ("drm/amd/display: Get replay info from VSDB")
