The qualcomm TLMM (top level mode manager) is their gpio/pinmux hardware controller. Although the pinmux is generic enough to use for the IPQ/APQ series chips, I'm directly calling the IPQ4018 routines to expedite bring-up. Notably, I'm not yet implementing the interrupt support - it's not required at this stage of bring-up. Differential Revision: https://reviews.freebsd.org/D33554
