We attempt to search for compatible strings which use a variable token in the documented name such as <chip> or <soc>. While this was attempted to be handled, it's utterly broken. The desired forms of matching are: vendor,<chip>-* vendor,name<part#>-* For <chip>, lower case characters and numbers are permitted. For <part#>, only numeric values are allowed. With this change, the number of missing compatible strings reported in arch/arm/boot/dts is reduced from 1071 to 960.
