rtw88: 8723d: initialize mac/bb/rf basic functions
Implement rtw_chip_ops::phy_set_param and ::mac_init to initialize mac/bb/rf, and they are used during interface up. The procedure contains power on sequence registers, download firmware, load predefined parameters, mac/bb/rf specific register and etc. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200422034607.28747-9-yhchuang@realtek.com
