* INTMUX channels below are somewhat arbitrary.
*
* The system timer (assumed at LPTMR0) is placed on channel 0, and peripherals
* are in channel 1. This can be overridden with overlays, e.g. to manage IRQ
* priorities, and it will Just Work, but using fewer channels here allows
* disabling unused ones in Kconfig, making the binary smaller.
*
* Each enabled channel requires 256 bytes in _sw_isr_table, so the savings for
* disabling channels can add up.
