Luke Starrett 58dff8f7ea hw/intc/arm_gicv3: Fix GICD_TYPER ITLinesNumber advertisement 
The ARM GICv3 TRM describes that the ITLinesNumber field of GICD_TYPER
register:

"indicates the maximum SPI INTID that the GIC implementation supports"

As SPI #0 is absolute IRQ #32, the max SPI INTID should have accounted
for the internal 16x SGI's and 16x PPI's.  However, the original GICv3
model subtracted off the SGI/PPI.  Cosmetically this can be seen at OS
boot (Linux) showing 32 shy of what should be there, i.e.:

    [    0.000000] GICv3: 224 SPIs implemented

Though in hw/arm/virt.c, the machine is configured for 256 SPI's.  ARM
virt machine likely doesn't have a problem with this because the upper
32 IRQ's don't actually have anything meaningful wired. But, this does
become a functional issue on a custom use case which wants to make use
of these IRQ's.  Additionally, boot code (i.e. TF-A) will only init up
to the number (blocks of 32) that it believes to actually be there.
