Subject: [PATCH net-next v6 1/5] net: stmmac: Add snps_id, dev_id to struct plat_stmmacenet_data

From: Jitendra Vegiraju <jitendra.vegiraju@...adcom.com>

Introduce new variables plat_stmmacenet_data::snps_id,dev_id to allow glue
drivers to specify synopsys ID and device id respectively.
These values take precedence over reading from HW register. This facility
provides a mechansim to use setup function from stmmac core module and yet
override MAC.VERSION CSR if the glue driver chooses to do so.
