Only Tegra234+ devices are currently supported and for these devices the
only DMA drivers that are supported for Linux are the Tegra210 ADMA and
Tegra186 GPCDMA drivers. Neither of these drivers ever supported the
'slave_id' parameter for configuring the DMA request ID for a given
channel. These drivers have always used device-tree to retrieve this
information. Only the Tegra20 APBDMA controller supported the 'slave_id'
field and this was dropped in Linux v5.17. The Tegra20 APBDMA driver was
supported in Tegra devices up until Tegra210, but starting with Tegra186
it is no longer supported.
Given that this is a legacy feature only supported for legacy Tegra
devices and drivers, drop the 'slave_id' support completely.
