b45c03f585 arm: Use g_new() & friends where that makes obvious sense 
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

f3c7d0389f hw: Fix qemu_allocate_irqs() leaks 
Replace qemu_allocate_irqs(foo, bar, 1)[0]
with qemu_allocate_irq(foo, bar, 0).

This avoids leaking the dereferenced qemu_irq *.
