wifi: ath12k: fix firmware assert during insmod in memory segment mode
In segment memory mode, firmware allocates memory segments of size
2 MB. This 2 MB memory is used by firmware for the number of peers.
This number of peer is sent from host to firmware during WMI init
command. For single-phy the number of peers sent is
TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number
of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) =
1058. With this 1058 number of peers firmware is unable to allocate
memory in 2 MB segment and firmware crash is observed.
Hence, fix this firmware crash by reducing the number of stations
TARGET_NUM_STATIONS for split-phy.
