PCI: cpcihp: Remove unused .get_power() and .set_power()

Browse Source 
The .get_power() and .set_power() function pointers in struct
cpci_hp_controller_ops were declared but never implemented by any
driver.

Thus, to improve code readability and reduce resource usage,
remove these pointers and the code that has never been used.
