Subject: aspeed: Register all watchdogs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f986ee1d43004a336197ee012e901f44bba04785;p=qemu.git

aspeed: Register all watchdogs

The ast2400 contains two and the ast2500 contains three watchdogs.
Add this information to the AspeedSoCInfo and realise the correct number
of watchdogs for that each SoC type.
