Fix for cpusensor going into D state. When PECI driver returns the error code EAGAIN, async_read_until will go into a keep trying again loop. As async_read_until does not handle EAGAIN reliably. Same issue was identified and fix for PSUSensor: https://github.com/openbmc/dbus-sensors/commit/bcf76717697238e380be785bd28150963ecf0e9e Fix for this is to use async_wait instead of async_read_until. Tested: In Intel system verified cpusensor daemon is not getting into D state when there is a peci error EAGAIN. Verified sensors are getting populated as expected when there is no PECI error.

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
