platform: amd: acp_7_x: add TDM invalid-index sentinel macros

Add ACP_TDM_INVALID_32 and ACP_TDM_INVALID_16 sentinel values to
both acp_7_0 and acp_7_x platform_misc.h.  These are used by the
TDM DAI and DMA drivers to mark unallocated channels/indices,
consistent with the existing SDW driver conventions.
