Change the handling of port F0h writes and FPU exceptions to implement IGNNE.
The implementation mixes a bit what the chipset and processor do in real
hardware, but the effect is the same as what happens with actual FERR#
and IGNNE# pins: writing to port F0h asserts IGNNE# in addition to lowering
FP_IRQ; while clearing the SE bit in the FPU status word deasserts IGNNE#.

There are three page size in qemu:
real host page size
host page size
target page size
All of them have dedicate variable to represent. For the last two, we
use the same form in the whole qemu project, while for the first one we
use two forms: qemu_real_host_page_size and getpagesize().
qemu_real_host_page_size is defined to be a replacement of
getpagesize(), so let it serve the role.

The biggest differences with the BCM2838 we are going to add, are
the base addresses of the interrupt controller and the peripherals.
Add these addresses in the BCM283XInfo structure to make this
block more modular. Remove the MCORE_OFFSET offset as it is
