rapidio/tsi721: fix mailbox resource reporting

Bug fix for Tsi721 RapidIO mport driver: Tsi721 supports four RapidIO
mailboxes (MBOX0 - MBOX3) as defined by RapidIO specification.  Mailbox
resources has to be properly reported to allow use of all available
mailboxes (initial version reports only MBOX0).

This patch is applicable to kernel versions staring from 3.2-rc1.
