boards: arm: mimxrt1060_evk: added additional PWM outputs

Browse Source 
Added PWM outputs to arduino header, to make testing PWM support with
this EVK simpler. These PWM outputs are enabled by the pwm_api test,
although they are not used. The user can enable the PWM shell in order
to test these PWM outputs.
