[PATCH] pwm: rockchip: simplify rockchip_pwm_get_state()

[Rasmus Villemoes]

The way state->enabled is computed is rather convoluted and hard to
read - both branches of the if() actually do the exact same thing. So
remove the if(), and further simplify "<boolean condition> ? true :
false" to "<boolean condition>".

I stumbled on this while trying to understand how the pwm subsystem
works. This patch is a semantic no-op, but it's also possible that,
say, the first branch simply contains a "double negative" so either
the != should be == or the "false : true" should be "true : false".
