ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.
Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.

The hwmgr module is responsible for messages sent to GAUDI F/W that are
not common to all habanalabs ASICs.
In GAUDI, we provide the user a simplified mode of controlling the ASIC
clock frequency. Instead of three different clocks, we present a single
clock property that the user can configure via sysfs.

The ability of setting power management properties by the system
administrator (through sysfs properties) is only relevant for the GOYA
ASIC. Therefore, move the relevant sysfs properties to the GOYA sysfs
specific file, to make the properties appear in sysfs only for GOYA cards.

This property has attempted to show the number of open file descriptors on
the device. This was a stupid and futile attempt so remove this property
completely.

This patch add the sysfs and hwmon entries that are exposed by the driver.
Goya has several sensors, from various categories such as temperature,
voltage, current, etc. The driver exposes those sensors in the standard
hwmon mechanism.
In addition, the driver exposes a couple of interfaces in sysfs, both for
configuration and for providing status of the device or driver.
The configuration attributes is for Power Management:
- Automatic or manual
- Frequency value when moving to high frequency mode
- Maximum power the device is allowed to consume
The rest of the attributes are read-only and provide the following
information:
- Versions of the various firmwares running on the device
- Contents of the device's EEPROM
- The device type (currently only Goya is supported)
- PCI address of the device (to allow user-space to connect between
/dev/hlX to PCI address)
- Status of the device (operational, malfunction, in_reset)
- How many processes are open on the device's file
