hw/watchdog/wdt_aspeed: Rename MMIO region size as 'iosize'

Avoid confusing two different things:
- the WDT I/O region size ('iosize')
- at which offset the SoC map the WDT ('offset')
While it is often the same, we can map smaller region sizes
at larger offsets.

Here we are interested in the I/O region size, so rename as
'iosize'.
