Bug Description
Newer dell systems come with a mic mute hotkey. Pressing the hotkey generates a BIOS event 0x150 but it is not handled but ignored by kernel.

In order to support mic_mute key, we need changes in both BIOS and dell-wmi as below:
1. BIOS needs to issue BIOS event 0x150 in WMI
2. BIOS needs to include an entry in SMBSIOS
3. dell-wmi.c needs to map the entry
1 and 2 should be true for dell systems with mic mute hotkey; however, a kernel patch is required for 3.
