Enhance NRF LOG to include line number in prefix

Hello,

I want to modify the NRF logging module to include the line number where the log was originated.

In the past I created a wrapper macro that called NRF_LOG_INFO twice, once with the desired prefix and one with the actual string I wanted to print. I also had to remove the new line characters from the logging module so that the two calls were printed in the same line. I don't want to do this wrapper stuff anymore and would like to modify the logging module instead.

What would be the best way to do this? I'm currently using SDK 15.2.
