Every RVU PF and VF is identified by HW using a 16bit PF_FUNC value. Due to the change in Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed. This patch handles the change by exporting PF,VF masks and shifts present in mailbox module to all other modules. Also moved the NIX AF register offset macros to other files which will be posted in coming patches.
