DWMAC driver was no longer selectable for stm32h7 series because of CONFIG_ETH_DWMAC dependency on DT_HAS_SNPS_DESIGNWARE_ETHERNET_MMU_ENABLED, which is only used for MMU based platforms. Restructure Kconfig to have user-selectable options for the platform-specific DWMAC drivers and select the common DWMAC driver accordingly. This way platform-specific dependencies can be tracked on these options, simplifying the logic. Signed-off-by: Tim Pambor <[email protected]>
Add a test case to build the Synopsys DesignWare MAC driver for STM32H7 series SoCs. This drivers is an alternative to the existing ETH_STM32_HAL driver. As such both drivers cannot be enabled at the same time. Signed-off-by: Tim Pambor <[email protected]>

The DWMAC driver was no longer selectable for STM32H7 series because of
CONFIG_ETH_DWMAC's dependency onDT_HAS_SNPS_DESIGNWARE_ETHERNET_MMU_ENABLED, which is only used for MMU based platforms.This PR restructures the Kconfig to have user-selectable options for the platform-specific DWMAC drivers and select the common DWMAC driver accordingly. This way platform-specific dependencies can be tracked on these options, simplifying the logic.
Additionally, the DWMAC driver has been included in the Ethernet build-all test suite to improve pipeline coverage and help prevent future regressions.
