pau: translation layer configuration

Next main part of the hypervisor PAU initialization.
The P10 PAU supports two OpenCAPI links.
The PAU provides various configuration selections for both of the OCAPI
Link Transaction Layer functions (OTLs). These include a link enable,
behavior controls, debug modes, and virtual channel credits to send to
the AFU. The OTL Configuration 0, OTL Configuration 1, OTL
Configuration 2, and TLX Credit Configuration registers are used to
control these functions.

This patch completes the PAU configuration following the
sections 17.1.3.4 to 17.1.3.10.2 of the workbook document.
