memory: fsl_ifc: populate child nodes of buses and mfd devices

Commit 3e25f800afb8 ("memory: fsl_ifc: populate child devices without
relying on simple-bus") was trying to replace the "simple-bus"
compatible with explicit bus populate in the driver.  But
of_platform_populate() only populates child nodes of ifc without
populating child buses and child mfd devices residing under ifc.  Change
it to of_platform_default_populate() to fix the problem.
