Subject: [net-next PATCH 4/7] stmmac: dwmac-sti: move st,gmac_en parsing to sti_dwmac_parse_data

The sti_dwmac_init() function is called both from probe and resume.
Since DT properties doesn't change between suspend/resume cycles move
parsing of this parameter into sti_dwmac_parse_data() where it belongs.
