An interrupt manager is implemented by emulating over pthreads.
Handlers are registered by QBMAN layer for being notified about
any interrupt request from DPAA blocks in userspace.

Existing devices and drivers depended on device ID rather than type.
A new enumerator for all DPAA2 devices is introduced in this patch.
At this point, the probe would not be able to link DPAA2 devices
with the driver and I/O would not work. Subsequent patches will
fix this.

The bus name was stored with embedded double quotes.
Indeed the bus name is given with a string in a macro,
which is not used elsewhere.
These macros are useless because the buses are drivers,
so they must not have any API for the application writer.
The registration can be done with a hardcoded value without quotes.
There is another (small) benefit of not using macros for driver names:
it is to have a meaningful constructor function name.
For instance, it was businitfn_PCI_BUS_NAME instead of businitfn_pci.
The bus registration macro is also changed to use
the new RTE_INIT_PRIO macro, similar to RTE_INIT used for other drivers.
The priority is the highest (101) in order to be sure that the bus driver
is registered before its device drivers.

-initializing Qman software portals
-building and sending portal commands
-portal interrupt configuration and processing
