[PATCH v3 04/10] of: base: move memory init from DT to initcall

[Marco Felsch]

From: Lucas Stach <dev at lynxeye.de>

Instead of calling it from of_probe, convert it to a initcall at
the appropriate level. This allows to move of_probe to later in
the init sequence while keeping the memory init at the same place,
which is important as many other drivers need the valid memory area
to be set up properly.
