irqchip/bmips: Replace cpumask_weight() with cpumask_empty()
bcm6345_l1_of_init() calls cpumask_weight() to check if any bit of a given
cpumask is set.
This can be done more efficiently with cpumask_empty() because
cpumask_empty() stops traversing the cpumask as soon as it finds first set
bit, while cpumask_weight() counts all bits unconditionally.
