BREAKING CHANGE: remove PWM_MULTICHAN option PWM_MULTICHAN option is redundant, we can just set CONFIG_PWM_NCHANNELS > 1. At default CONFIG_PWM_NCHANNELS is set to 1, so the default behavior is preserved. Access to single channel API is now `info->channels[0].XXX` instead of `info->XXX` This is the first step to simplify PWM implementation and make it more portable.

CI for this PR and apps part (https://github.com/raiden00pl/manual-nuttx-ci/actions/runs/25676150035) pass: https://github.com/raiden00pl/manual-nuttx-ci/actions/runs/25676150035 If we merge this before release 13.0, I can try to separate common PWM driver from pulse count PWM, as discussed here: #12381 (comment) |

So this is one of those PRs that needs apps + kernel merge at once? Looks good to me! |

Impact
simplify API, no functional changes. old
CONFIG_PWM_MULTICHAN=nis now achieved withCONFIG_PWM_NCHANNELS = 1Testing
