This significantly reduces the firmware size and also makes it possible to compile the firmware for a smaller 8Kbyte flash device (stm8sblue), where the firmware is only 565 bytes big, compared to the over 21kByte before.

For the environments

stm8sblue
stm8sdisco
nucleo_8s207k8
nucleo_8s208rb

with the old config file:

Error: The program size (21730 bytes) is greater than maximum allowed (8192 bytes)
*** [checkprogsize] Explicit exit, status 1
RAM:   [          ]   0.0% (used 0 bytes from 1024 bytes)
Flash: [==========]  265.3% (used 21730 bytes from 8192 bytes)

RAM:   [          ]   0.0% (used 0 bytes from 2048 bytes)

Flash: [==        ]  22.2% (used 29062 bytes from 131072 bytes)

With my updated file:

RAM:   [          ]   0.0% (used 0 bytes from 1024 bytes)
Flash: [=         ]   6.9% (used 565 bytes from 8192 bytes)

RAM:   [          ]   0.0% (used 0 bytes from 6144 bytes)
Flash: [          ]   0.9% (used 569 bytes from 65536 bytes)

RAM:   [          ]   0.0% (used 0 bytes from 6144 bytes)
Flash: [          ]   0.4% (used 571 bytes from 131072 bytes)

The resulting firmare still works on my STM8S103F3 board.

GPIOG doesn't exist and would result in build failure.
