net: stmmac: add support for platform specific reset
This patch adds support for platform-specific reset logic in the
stmmac driver. Some SoCs require a different reset mechanism than
the standard dwmac IP reset. To support these platforms, a new function
pointer 'fix_soc_reset' is added to the plat_stmmacenet_data structure.
The stmmac_reset in hwif.h is modified to call the 'fix_soc_reset'
function if it exists. This enables the driver to use the platform-specific
reset logic when necessary.
