meta-ampere: power control: restructure source code

ampere-hostctrl package includes the generic codes and the platform
specific codes. The generic sources are applied for all of the Ampere
platforms, they are the service files and the scripts to setting the
GPIO pins. The platform specific sources are the GPIO pin config file
and the gpio monitor config files.
This commit moves the platform specific files to the platform code.

Tested:
    1. Do the power control actions use ipmitool, BMC web and Redfish.
    2. Make sure the server states are changed as expected.
