The function ath12k_mac_copy_sband_iftype_data() is currently
used HE capabilities propagation but it can be extended to
include EHT data. Move the HE specific functionality from to
ath12k_mac_copy_he_cap() to make EHT additions easier.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
