[Impact]
Need this patch in so a BIOS upgrade won't cause issues on HP laptops.

platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi
After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
strange char "^@" which printed out every second and makes login
nearly impossible. Also the below messages were shown both in console
and journal/dmesg every second:
usb 1-3: Device not responding to setup address.
usb 1-3: device not accepting address 4, error -71
usb 1-3: device descriptor read/all, error -71
usb usb1-port3: unable to enumerate USB device
Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi. At the end it was
fixed by removing hp_wmi module.
The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

[Test case]
test on a HP laptop with the new BIOS
[Where problems could occur]
from the commit:
* In pre-2009 BIOS, command 1Bh return 0x4 to indicate that
* BIOS no longer controls the power for the wireless
* devices. All features supported by this command will no
* longer be supported.
anyone running a laptop with obsolete pre-2009 BIOS probably won't
notice the missing feature at this point.
