wifi: rtw89: use firmware offload for PHY and RF batch register writes
Use firmware offload to perform batch register writes for PHY and RF.
This reduces I/O operations, improves bus transfer efficiency, and
decreases hardware initialization time.
Performance improvement on USB 2.0 HCI:
- rtw89_phy_init_bb_reg: 61 ms -> 5 ms
- rtw89_phy_init_rf_reg: 587 ms -> 106 ms
Use offload-aware delay functions (do_udelay and do_mdelay) for the
delay calls in rtw89_phy_init_reg, rtw89_phy_config_rf_reg, and
rtw89_phy_config_rf_reg_v1 to ensure compatibility with batch register
writes.
