pwm: lp3943: Dynamically allocate PWM chip base
[ Upstream commit5.4-rM2-2.2.x-imx-squashed1f0f1e80fd
] When there are other PWM controllers enabled along with pwm-lp3943, pwm-lp3942 is failing to probe with -EEXIST error. This is because other PWM controllers are probed first and assigned PWM base 0 and pwm-lp3943 is requesting for 0 again. In order to avoid this, assign the chip base with -1, so that it is dynamically allocated. Fixes:af66b3c093
