wifi: ath12k: add hardware parameters for maximum supported clients

Browse source

Currently, the driver uses memory profile parameters to determine the
maximum number of supported clients, with a default limit of 512 for
single-radio and 128 for DBS and DBS+SBS configurations. However,
some devices have lower hardware limits depending on the radio
configuration. Exceeding these hardware-specific limits can lead to
firmware crashes.

Add hardware parameters in ath12k_hw_params to define the maximum supported
clients for each radio configuration. The driver uses the minimum of the
memory profile limit and the hardware capability limit to prevent exceeding
hardware constraints.
