pwm: ab8500: Explicitly allocate pwm chip base dynamically
[ Upstream commit 5e5da1e9fbeecdf9d7a7495d7ae2a37453e38499 ]
The ab8500 driver is the last one which doesn't (explicitly) use dynamic
allocation of the pwm id. Looking through the kernel sources I didn't
find a place that relies on this id. And with the device probed from
device tree pdev->id is -1 anyhow; making this explicit looks
beneficial, too.
