Subject: [PATCH net] net: stmmac: platform: fix the incorrect parameter

The second parameter of stmmac_pltfr_init() needs the pointer of
"struct plat_stmmacenet_data". So, correct the parameter typo when calling the
function.

Otherwise, it may cause this alignment exception when doing suspend/resume.
