occ: Send self-interrupt to chip with active PSI

We were previously asking the OCC of the current chip to generate
the self interrupt. If Hostboot does not configure all the PSI Host
Bridges, so if the current chip happens to have an unconfigured PSI HB,
the chip will never see the interrupt.

Instead grab a chip id from the list of configured PSIs, and ask the OCC
on that chip to generate the self-interrupt.

This adds a pointer to the chip's PSI in struct proc_chip so we can
use the current chip's PSI if it is active without having to look
through all of them.
