wifi: rtw89: wow: only WiFi 6 chips initialize RF registers in WoWLAN mode

Browse source

Only the WiFi 6 chips need to initialize RF register when WoWLAN download
FW for some power save issue. Applying the same initialization flow to
WiFi 7 chips might trigger the error
'RF parameters exceed size. path=1, idx=1500.'.

This happens because normal mode uses rtw89_phy_config_rf_reg_v1(), which
skips registers with addresses below 0x100. However, WoWLAN mode uses
rtw89_phy_config_rf_reg_noio(), and WiFi 7 chips do not satisfy the
rtw89_chip_rf_v1() condition. As a result, more RF registers are
configured, causing the size overflow error.
