misc: retire the old BMP085 driver

Patches merged to the IIO BMP085 driver makes it fully compliant
with all features found in this old misc driver. Retire this old
driver in favor of the new one in the proper subsystem.

-What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
-Date:		June 2010
-Contact:	Christoph Mair <christoph.mair@gmail.com>
-Description:	Start a pressure measurement and read the result. Values
-		represent the ambient air pressure in pascal (0.01 millibar).
-
-		Reading: returns the current air pressure.

-What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input
-Date:		June 2010
-Contact:	Christoph Mair <christoph.mair@gmail.com>
-Description:	Measure the ambient temperature. The returned value represents
-		the ambient temperature in units of 0.1 degree celsius.
-
-		Reading: returns the current temperature.
-
-
-What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
-Date:		June 2010
-Contact:	Christoph Mair <christoph.mair@gmail.com>
-Description:	Tell the bmp085 to use more samples to calculate a pressure
-		value. When writing to this file the chip will use 2^x samples
-		to calculate the next pressure value with x being the value
-		written. Using this feature will decrease RMS noise and
-		increase the measurement time.
-
-		Reading: returns the current oversampling setting.
-
-		Writing: sets a new oversampling setting.
-		Accepted values: 0..3.

- *  This driver supports the bmp085 and bmp18x digital barometric pressure
- *  and temperature sensors from Bosch Sensortec. The datasheets
- *  are available from their website:
- *  http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
- *  http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP180-DS000-07.pdf
- *
- *  A pressure measurement is issued by reading from pressure0_input.
- *  The return value ranges from 30000 to 110000 pascal with a resulution
- *  of 1 pascal (0.01 millibar) which enables measurements from 9000m above
- *  to 500m below sea level.
- *
- *  The temperature can be read from temp0_input. Values range from
- *  -400 to 850 representing the ambient temperature in degree celsius
- *  multiplied by 10.The resolution is 0.1 celsius.
- *
- *  Because ambient pressure is temperature dependent, a temperature
- *  measurement will be executed automatically even if the user is reading
- *  from pressure0_input. This happens if the last temperature measurement
- *  has been executed more then one second ago.
- *
- *  To decrease RMS noise from pressure measurements, the bmp085 can
- *  autonomously calculate the average of up to eight samples. This is
- *  set up by writing to the oversampling sysfs file. Accepted values
- *  are 0, 1, 2 and 3. 2^x when x is the value written to this file
- *  specifies the number of samples used to calculate the ambient pressure.
- *  RMS noise is specified with six pascal (without averaging) and decreases
- *  down to 3 pascal when using an oversampling setting of 3.
