2025-02-12lib: utils: Initialize miscellaneous drivers in one passSamuel Holland1-4/+1
For driver subsystems that are not tightly integrated into the OpenSBI init sequence, it is not important that the drivers are initialized in any particular order. By putting all of these drivers in one array, they can all be initialized with a single pass through the devicetree. This saves about 10 ms of boot time on HiFive Unmatched.
