[PATCH] power: sequencing: print power sequencing device parent in debugfs

[Chen-Yu Tsai]

The debugfs summary currently shows the power sequencing device's name.
This is not really helpful since the device name is always "pwrseq.N".

Also print the parent device's name. This would likely be the device
node name from the device tree, something like "nvme-connector". This
would make it much easier for the developer to associate the summary
with a certain device.
