lib: utils/mailbox: Parse P2A doorbell system MSI index from DT

Browse Source 
The P2A doorbell system MSI index is expected to be discovered from
device tree instead of RPMI system MSI service group attribute. This
is based on ARC feedback before RPMI spec was frozen.

Let's parse P2A doorbell system MSI index from device tree and also
expose it as rpmi channel attribute to RPMI client drivers.
