macfb: update macfb.c to use the Error API best practices
As per the current Error API best practices, change macfb_commom_realize() to return
a boolean indicating success to reduce errp boiler-plate handling code. Note that
memory_region_init_ram_nomigrate() is also updated to use &error_abort to indicate
a non-recoverable error, matching the behaviour recommended after similar
discussions on memory API failures for the recent nubus changes.
