Instead of checking the bits that give the internal machine state we can simply rely on the information from the other bits: 1) on or off, 2) transitioning or not.
Bit 31 has the "Panel Power On Status" Bits 29:28 has the "Power Sequence Progress" So, wait_panel_on() only needs to wait for bit 31 to indicate it's on and bits 29:28 to indicate there's no transition in progress. From my limited test that includes the cycle delay, so we are safe with only checking those bits, like we do in wait_panel_off(). Admittedly this needs more test, so let CI go through more platforms.
