pwm: bcm2835: Dynamically allocate base
[ Upstream commit5.4-rM2-2.2.x-imx-squashed2c25b07e5e
] 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:e5a06dc5ac
