pwm: lpc32xx: correct number of PWM channels from 2 to 1
LPC32xx SoC has two independent PWM controllers, they have different clock parents, clock gates and even slightly different controls, and each of these two PWM controllers has one output channel. Due to almost similar controls arranged in a row it is incorrectly set that there is one PWM controller with two channels, fix this problem, which at the moment prevents separate configuration of different clock parents and gates for both PWM controllers. The change makes previous PWM device node description incompatible with this update. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
