habanalabs: add debugfs support
This patch adds debugfs support to the driver. It allows the user-space to display information that is contained in the internal structures of the driver, such as: - active command submissions - active user virtual memory mappings - number of allocated command buffers It also enables the user to perform reads and writes through Goya's PCI bars.

Description: Allows the root user to read or write directly through the

device's PCI bar. Writing to this file generates a write
|

transaction while reading from the file generates a read
|
||||
transcation. This custom interface is needed (instead of using
|
||||
the generic Linux user-space PCI mapping) because the DDR bar
|
||||
is very small compared to the DDR memory and only the driver can
|
||||
move the bar before and after the transaction
