Subject: [PATCH] misc/bmp085: Enable building as a module

Commit 985087dbcb02 'misc: add support for bmp18x chips to the bmp085
driver' changed the BMP085 config symbol to a boolean. I see no
reason why the shared code cannot be built as a module, so change it
back to tristate.

There is no reason for building the common code stand-alone. The BMP085
config option is only selectable via the BMP085_I2C/_SPI options.
See the select-statement for those options:

config BMP085_I2C
tristate "BMP085 digital pressure sensor on I2C"
select BMP085
...

Yes, but it is then always built-in.

Life is like a sewer:
what you get out of it depends on what you put into it.

Good point. This change is fine by me.
