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

This patch adds the basic part of Goya's H/W initialization. It adds code
that initializes Goya's internal CPU, various registers that are related to
internal routing, scrambling, workarounds for H/W bugs, etc.
It also initializes Goya's security scheme that prevents the user from
abusing Goya to steal data from the host, crash the host, change
Goya's F/W, etc.

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.
