ARM: dts: rockchip: fixes the emmc error on rk3036 SoCs

Browse Source 
As the emmc is supplyed power by vcc_io, that's 3.3v voltage.
the default 1.8v volatge will cause the emmc error. as the following:

[   17.096082 ] mmcblk1: error -115 sending stop command, original cmd
response 0x900, card status 0xb00
[   17.127022 ] mmcblk1: error -110 transferring data, sector 664720, nr
72, cmd response 0x900, card status 0xb00

Remove the mmc-ddr-1_8v to keep the default the 3.3v voltage.
