Subject: [PATCH v2 3/3] ARM: at91: remove unnecessary
of_platform_default_populate calls
The DT core will call of_platform_default_populate, so it is not
necessary for machine specific code to call it unless there are custom
match entries, auxdata or parent device. Neither of those apply here, so
remove the call.
