Ivan Grokhotkov 1c60a0450e Merge branch 'bugfix/driver_cleanup_log' into 'master' 
drivers: remove file paths from log statements

Function name and error string are usually sufficient to find the place which has triggered an error. 

`__FILE__` macro generates a string which has absolute file name (with our build system), which add many long strings to the program binary.

Also change log tags to lower case to match style used elsewhere.

Fixes https://github.com/espressif/esp-idf/issues/126
