pau: hmi scom dump
This patch add a new function to dump PAU registers when a HMI has been
raised and an OpenCAPI link has been hit by an error.
For each register, the scom address and the register value are printed.
The hmi.c has been redesigned in order to support the new PHB/PCIEX
type (PAU OpenCapi). Now, the *npu* functions support NPU and PAU units of
P8, P9 and P10 chips.
