PCI: shcphp: remove 'name' parameter

Browse Source 
We do not need to manage our own name parameter, especially since
the PCI core can change it on our behalf, in the case of duplicate
slot names.

Remove 'name' from shpchp's version of struct slot.

This change also removes the unused struct task_event from the
slot structure.
