obp-tftp: Remove the ciregs-buffer
When a secondary boot loader like Yaboot tries to load additional files
like the kernel image via TFTP, SLOF internally started the net-snk as a
second client to do the TFTP transfer. So there were suddenly two clients
using the Open Firmware client interface at the same time. Thus the
obp-tftp code had to save the client interface registers from yaboot
before jumping into the net-snk client, and restore them afterwards.
Since we're now not using net-snk for the network loading anymore, we
also don't need to buffer the register contents of the client anymore.
