[coreboot] T60: Beeping for the battery states

Dear coreboot folks,

the proprietary BIOS allows to disable/mute sound, when battery status
is low or the power cable is plugged in or out.

Is it possible to configure that with coreboot or ectool [1]?

        src/ec/lenovo/h8 $ tail -9 h8.h
        #define H8_EVENT_BAT0		0x4a
        #define H8_EVENT_BAT0_STATE	0x4b
        #define H8_EVENT_BAT1		0x4c
        #define H8_EVENT_BAT1_STATE	0x4d
        #define H8_EVENT_FN_F5 0x64
        #define H8_EVENT_FN_F6 0x65
        src/mainboard/lenovo/t60 $ git grep -i mute
        acpi/platform.asl:      \_SB.PCI0.LPCB.EC.MUTE(1)
