Subject: [PATCH v1 05/10] x86/platform/intel-mid: Remove unused leftovers (msic_power_btn)
There is no driver present, remove the device creation and other leftovers.
Note, for Intel Merrifield there is another driver which is instantiated by
a certain MFD one and does not need any support from device_libs.
