pwm: bcm2835: Dynamically allocate base
The newer 2711 and 7211 chips have two PWM controllers and failure to
dynamically allocate the PWM base would prevent the second PWM
controller instance being probed for succeeding with an -EEXIST error
from alloc_pwms().
Fixes: e5a06dc5ac1f ("pwm: Add BCM2835 PWM driver")
