ipc4: base_fw: Request empty Astate table

[wjablon1]

Improve IPC4 compatibility in respect to the Astate table that is received by FW as a part of set_large_config IPC. The table contains maximal KCPS thresholds, one for each supported clock source. Currently SOF FW performs autonomous management of clock sources and does not take such a configuration into account. Despite this, FW reports through get_large_config its support for 3 elements of Astate table. This change sets the supported Astate table size to 0. Also, as a corner case, a trivial handler is added for handling the empty table.

Looks like issue with static assert. From reddit: “ you can't declare a variable on the line immediately after a case x: unless the whole case block is scoped with brackets” I will fix this.
