hwmon: (lis3) add axes module parameter for custom axis-mapping
The axis-mapping of lis3dev device on many (rather most) HP machines
doesn't follow the standard. When each new model appears, users need to
adjust again. Testing this requires the rebuild of kernel, thus it's not
trivial for end-users.
This patch adds a module parameter "axes" to allow a custom axis-mapping
without patching and recompiling the kernel driver. User can pass the
parameter such as axes=3,2,1. Also it can be changed via sysfs.
