Fix barometer I2C address redefine issues

[Minderring]

Dear INAV developers,

PR #9902 adds configuration symbol for barometer I2C address. When defining the address in target.h with the same symbol as barometer driver files, it causes a redefined error. And this PR is to fix the issues.

Best Regard!

I see there are currently no I2C_ADDR defines in any targets.

$ egrep -Hinr '_I2C_ADDR' src/main/target/*/
$

Is there a need to start doing that?

Hi! I attempted to define the I2C_ADDR but encountered a redefine error. My later PR #10557 utilized the I2C_ADDR.

Currently, there are no I2C_ADDR definitions in any targets, as most boards use the default address. Others, using like BUSDEV_REGISTER_I2C(busdev_qmc5883, DEVHW_QMC5883, MAG_I2C_BUS, 0x0D, NONE, DEVFLAGS_NONE);, to specify a non-default address.

I believe it would be better to address this issue to prevent future problems.

Thank you!
