stmmac: platform: Move plat_dat checking earlier
Original code only check/alloc plat_dat for the CONFIG_OF case, this
patch check/alloc it earlier and unconditionally to avoid kernel build
warnings:
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c:275
stmmac_pltfr_probe() warn: variable dereferenced before check 'plat_dat'
V2: Fix coding style.
