The i8254 timer control IO port (0x43) should be setup correctly by using PIT counter 2 to generate beeps, however in U-Boot other codes like TSC driver utilizes PIT for TSC frequency calibration and configures the counter 2 to a different mode that does not beep. Fix this by always ensuring the PIT counter 2 is correctly initialized so that the i8254 beeper driver works as expected.
