AVR GPIO macro defines more readable (#5937)
* A little easier to read the definition of the GPIO control macro for AVR. No change in build result. * Changed to not use GNU statement expression extension. No change in build result. * Modified split_common/serial.c to use qmk_firmware standard GPIO control macro. No change in build result. * fix PE6 -> E6 * remove some space * add some comment to config_common.h * Changed split_common/serial.c to use a newer version of qmk_firmware standard GPIO control macro.
