Initialize static variable ath11k_mhi_config for all hw_rev,
return error for unknown hw_rev.
This patch fixes below Smatch warning:
drivers/net/wireless/ath/ath11k/mhi.c:357 ath11k_mhi_register()
error: uninitialized symbol 'ath11k_mhi_config'.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1
Fixes: a233811ef600 ("ath11k: Add qcn9074 mhi controller config")
