Hi, all.

I have PCISA-LX-800 board (AMD LX800 + CS5536)

With coreboot bios pc speaker not work on Linux.
But with vendor BIOS pc speaker work on Linux OK.

The CS5536 datasheet say:
Legacy PC/AT Speaker Beep is only available when GPIO1 is programmed
to OUT_AUX1.
The coreboot not enable pc speaker output on cs5536.

This patch enable pc speaker output on cs5536 based devices.
