Subject: [PATCH] hwdb: restore comments about MSI devices

Some time ago 95-keymap.rules was replaced by
60-keyboard.hwdb. Original comments for MSI laptops (that were in
95-keymap.rules) were removed, but I think they are important for
understanding what's going on.

(cherry picked from commit 288026bda90245ae6523441ce308d58ad1caefc8)
