habanalabs: add support for notification via eventfd
The driver will be able to send notification events towards
a user process, using user's registered event file descriptor.
The driver uses the notification mechanism to inform the
user about an occurred event.
A user thread can wait until a notification is received from
the driver.
The driver stores the occurred event until the user reads it,
using HL_INFO_GET_EVENTS - new ioctl opcode in the INFO ioctl.
Gaudi specific implementation includes sending a notification
on a TPC assertion event that is received from f/w.
