Integration of the GPIO Module

The GPIO module connects the top level modules to the GPIO pins. It is also connected
to the APB bus. The GPIO module is operated with the APB clock.
The feature of an internal GPIO "reset disable" is activated in ERTEC 200P (module
input: XRESET_HW
(XRESET_GPIO_SM), a selective reset in GPIO_SM is also possible.
The connection of the internal modules to the GPIO module (GPIO_XOE_F_A/B/C,
GPIO_OUT_F_A/B/C, GPIO_IN_F_A/B/C, GPIO_IN_F_A/B/C_BLOCK signals) is de-
scribed in the corresponding modules and in GPIO assignment.
