[PATCH 3/7] hw/arm/raspi4b: Split raspi4b_machine_class_init() in two (1g and 2g)

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Current raspi4b_machine_class_init() method register 2 distinct
machines, with different board revision (thus different memory
size), whether the host is 32-bit or more. Split it as 2 new
methods, one for the raspi4b with 1GB of memory (on 32-bit hosts)
and another for the raspi4b with 2GB of memory.
