[PATCH] ARM: shmobile: kzm9g dts: Add adxl345-specific compatible property

[Geert Uytterhoeven]

The accelerometer node used the generic compatible property only.
Add the device-specific one, to make it future proof.

Depends on commit 3a38958d2477b718 ("Input: adxl34x - add OF match
support"), which is in v4.2-rc1.

"adi,adxl34x" is deprecated and shouldn't be used in DT. You can just specify 
"adi,adxl345".

Right, we only care (sometimes ;-) about backward-compatibility,
not about forward-compatibility.
