[PATCH] firmware: cleanup FIRMWARE_IN_KERNEL message

["Robin H. Johnson" <robbat2@gentoo.org>]

The help for FIRMWARE_IN_KERNEL still references the firmware_install
command that was recently removed by commit 5620a0d1aacd ("firmware:
delete in-kernel firmware").

Clean up the message to direct the user to their distribution's
linux-firmware package, and remove any reference to firmware being
included in the kernel source tree.

-	  The kernel source tree includes a number of firmware 'blobs'

-	  use these is to run "make firmware_install", which, after

-	  binary files in firmware/ to /lib/firmware/ on your system so
-	  that they can be loaded by userspace helpers on request.

 	  Enabling this option will build each required firmware blob
