Subject: [PATCH v1 1/2] x86/platform/intel_mid_pci: Remove duplicate power off

Intel MID platforms (Moorestown, Medfield, Clovertrail, Merrifield) are sharing
the code in intel_mid_pci.c module. There is no need to power off specific
Moorestown devices after commit 5823d0893ec2 ("x86/platform/intel-mid: Add Power
Management Unit driver") because the condition in mrfld_power_off_dev() is true
for any platform from the above list.

Remove duplicate power off certain devices on Intel Moorestown and rename
functions to show that they are applied to any of Intel MID platforms.
