Subject: next-cube: don't use rtc phase value of -1
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=501b5099f69e75520fc1d6368c44c42ebe337ddc;p=qemu.git

next-cube: don't use rtc phase value of -1

The rtc phase value of -1 is directly equivalent to using a phase value of 0 so
simplify the logic to use an initial rtc phase of 0.
