Now that we have a subsystem for compute accelerators, move the
habanalabs driver to it.
This patch only moves the files and fixes the Makefiles. Future
patches will change the existing code to register to the accel
subsystem and expose the accel device char files instead of the
habanalabs device char files.
Update the MAINTAINERS file to reflect this change.

currently we support only 2 asids in all asics.
asid 0 for driver, and asic 1 for user.
no need to setup 1024 asids configurations at init phase.

Users and sysadmins usually want to know what is the device utilization as
a level 0 indication if they are efficiently using the device.
Add a new opcode to the INFO IOCTL that will return the device utilization
over the last period of 100-1000ms. The return value is 0-100,
representing as percentage the total utilization rate.

This will prevent unneeded include of header files, which may increase
compilation time.

This patch adds a basic support for the Goya device. The code initializes
the device's PCI controller and PCI bars. It also initializes various S/W
structures and adds some basic helper functions.
