docs: ABI: cleanup several ABI documents
There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

the name of the method by which the system will be put to

'firmware' - means that the memory image will be saved to disk
by some firmware, in which case we also assume that the
firmware will handle the system suspend.

'platform' - the memory image will be saved by the kernel and
the system will be put to sleep by the platform driver (e.g.
ACPI or other PM registers).

the system will be powered off.

'reboot' - the memory image will be saved by the kernel and
the system will be rebooted.
