[ Upstream commit d078f5857a00c06fa0ddee26d3cb722e938e1688 ]
Driver selects firmware by hardware version, which normally can be read from registers before selecting firmware. However, certain chips such as RTL8851B, it needs to read hardware version from efuse while doing power_on, but do power_on after selecting firmware in current flow.
To resolve this flow problem, move power_on out from rtw89_mac_partial_init(), and call rtw89_mac_pwr_on() separately at proper places to have expected flow.
