net: dwc_eth_qos: add Kconfig option to select supported configuration

Browse Source 
Add configuration flag to select the supported dwc driver configuration:
- CONFIG_DWC_ETH_QOS_TEGRA186
- CONFIG_DWC_ETH_QOS_IMX
- CONFIG_DWC_ETH_QOS_STM32

See Linux driver ethernet/stmicro/stmmac and associated glue layers
for other configuration examples.

This patch removes the not-selected compatibles and lets the linker remove
the unused functions to reduce the size of the driver.

This driver supports the Synopsys Designware Ethernet QOS (Quality
Of Service) IP block. The IP supports many options for bus type,
clocking/reset structure, and feature list. This driver currently
supports the specific configuration used in NVIDIA's Tegra186 chip,
but should be extensible to other combinations quite easily.
