hw/core/or-irq: Fix incorrect assert forbidding num-lines == MAX_OR_LINES
The num-lines property of the TYPE_OR_GATE device sets the number
of input lines it has. An assert() in or_irq_realize() restricts
this to the maximum supported by the implementation. However we
got the condition in the assert wrong: it should be using <=,
because num-lines == MAX_OR_LINES is permitted, and means that
all entries from 0 to MAX_OR_LINES-1 in the s->levels[] array
are used.
We didn't notice this previously because no user has so far
needed that many input lines.
