ath11k: fix wmi init configuration

BugLink: https://bugs.launchpad.net/bugs/1910111
[ Upstream commit 36c7c640ffeb87168e5ff79b7a36ae3a020bd378 ]

Assign the correct hw_op ath11k_init_wmi_config_ipq8074 to
the hw IPQ8074. Also update the correct TWT radio count.
Incorrect TWT radio count cause TWT feature fails on radio2
because physical device count is hardcoded to 2. so set
the value dynamically.

Found this during code review.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2
