hw/misc/macio: Rename sysbus_dev to sbd for consistency and brevity 

Some functions use sysbus_dev while others sbd name for local variable
storing a sysbus device pointer. Standardise on the shorter name to be
consistent and make the code easier to read as short name is less
distracting and needs less line breaks.
