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.
