wifi: ath11k: thermal: don't try to register multiple times

Browse Source 
Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which
ends up calling ath11k_thermal_register(). So we try to register thermal
devices multiple times. And when we power off the firmware during
suspend/hibernation (implemented in the next patch) we get a warning in resume:

hwmon hwmon4: PM: parent phy0 should not be sleeping

Workaround this similarly like ath11k_mac_register() does by testing
ATH11K_FLAG_REGISTERED.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
