[PATCH 9/9] soundwire: amd: consolidate revision-specific probe setup

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

Determine port counts first via a switch on acp_rev, compute max_ports,
then consolidate all remaining revision-specific assignments
(mmio offset, bus ops, port ops, compute_params, and port_offset_map
allocation) into a single second switch. Both switches reject unknown
revisions with dev_err() and -EINVAL, keeping each switch
self-contained so an incomplete addition of a new revision is caught
at whichever switch it is missing from.

cols_index and rows_index are no longer initialised at probe time;
acp_sdw_clk_init_ctrl() sets them from the actual bus clock and frame
shape before amd_acp63_sdw_set_frameshape() is ever called, so no
early initialisation is needed.
