I'm going to make this a module parameter instead and get rid of the 
constant. The reason, I have this default parameter today is that QEMU 
does not support passing device tree arguments for platform devices.

QEMU allows you to set memory and interrupt resources only for platform 
devices.

At least now, I can pass the argument via command line before starting QEMU.

I'll put checks that the value needs to come from either 
DTS/ACPI/command line.
