Pedro F. Giffuni 718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags. 
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

*
* The scheme used for probing cards faces these problems:
* It is impossible to work out which type of tuner is actually fitted,
* (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
* It is impossible to determine what audio-mux hardware is connected.
* It is impossible to determine if there is extra hardware connected to the
* GPIO pins (eg radio chips or MSP34xx reset logic)
*
* However some makes of card (eg Hauppauge) come with a configuration eeprom
* which tells us the make of the card. Most eeproms also tell us the
* tuner type and other features of the cards.
*
* The current probe code works as follows
* A) If the card uses a Bt878/879:
* 1) Read the sub-system vendor id from the configuration EEPROM.
* Select the required tuner, audio mux arrangement and any other
* onboard features. If this fails, move to step B.
* B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
* 1) Look for I2C devices. If there are none fitted, it is an Intel or
* VideoLogic cards.
* 2) Look for a configuration EEPROM.
* 2a) If there is one at I2C address 0xa0 it may be
* a Hauppauge or an Osprey. Check the EEPROM contents to determine which
* one it is. For Hauppauge, select the tuner type and audio hardware.
* 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
* We still have to guess on the tuner type.
*
* C) If we do not know the card type from (A) or (B), guess at the tuner
* type based on the I2C address of the tuner.
*
* D) After determining the Tuner Type, we probe the i2c bus for other
* devices at known locations, eg IR-Remote Control, MSP34xx and TDA
* stereo chips.
