[PATCH 20/49] irq: mips: replace cpumask_weight with cpumask_empty where appropriate

[Yury Norov]

bcm6345_l1_of_init() calls cpumask_weight() to check if any bit of a given
cpumask is set. We can do it 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.
