IntelCPUSensor: support new Linux PECI API

The upstream PECI bus implementation doesn't support any ioctl() or
other means to send and receive PECI messages directly from the
userspace, instead it only provides regular kernel-level abstractions
(just hwmon CPU and DIMM temperature devices for now). It also requires
the userspace to trigger bus rescan after the CPU(s) are powered on.

This patch makes IntelCPUSensor automatically detect and use the new
API.
