PM: Rename struct pm_ops and related things

Browse Source 
The name of 'struct pm_ops' suggests that it is related to the power
management in general, but in fact it is only related to suspend.   Moreover,
its name should indicate what this structure is used for, so it seems
reasonable to change it to 'struct platform_suspend_ops'.   In that case, the
name of the global variable of this type used by the PM core and the names of
related functions should be changed accordingly.

/sys/power/disk controls the operating mode of the suspend-to-disk
mechanism. Suspend-to-disk can be handled in several ways. We have a
few options for putting the system to sleep - using the platform driver
(e.g. ACPI or other pm_ops), powering off the system or rebooting the
(e.g. ACPI or other suspend_ops), powering off the system or rebooting the
system (for testing).
Additionally, /sys/power/disk can be used to turn on one of the two testing
