[PATCH v4 2/9] hw/arm/bcm2836: QOM'ify more by adding class_init() to each SoC type

[Philippe Mathieu-Daudé]

Remove usage of TypeInfo::class_data. Instead fill the fields in
the corresponding class_init().

So far all children use the same values for almost all fields,
but we are going to add the BCM2711/BCM2838 SoC for the raspi4
machine which use different fields.
