CPT RVU Local Functions(LFs) needs to be attached to the
PF/VF to submit the instructions to CPT.
This patch adds the interface to initialize and attach
the LFs. It also adds interface to register the LF's
interrupts.

CPT includes microcoded GigaCypher symmetric engines(SEs), IPsec
symmetric engines(IEs), and asymmetric engines (AEs).
Each engine receives CPT instructions from the engine groups it has
subscribed to. This patch loads microcode, configures three engine
groups(one for SEs, one for IEs and one for AEs), and configures
all engines.

Adds 'sriov_configure' to enable/disable virtual functions (VFs).
Also Initializes VF<=>PF mailbox IRQs, register handlers for
processing these mailbox messages.
Admin function (AF) handles resource allocation and configuration for
PFs and their VFs. PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a mailbox
region. The PF then forwards these messages to the AF. After handling
the request, the AF sends a response back to the VF, through the PF.
This patch adds support for this 'VF <=> PF <=> AF' mailbox
communication.

In the resource virtualization unit (RVU) each of the PF and AF
(admin function) share a 64KB of reserved memory region for
communication. This patch initializes PF <=> AF mailbox IRQs,
registers handlers for processing these communication messages.
