ARM: mach-imx: imx6sx: Remove Ethernet refclock setting

Browse Source 
The Ethernet refclock configuration is board specific and should
not be harcoded in machine code.

Remove it to align with the imx6ul commit e87f3be1c7 ("ARM: mach-imx:
imx6ul: remove not optional ethernet refclock overwrite").

Clearing bits 13 and 17 of GPR1 is the POR values, so this change
does not affect existing boards in mainline.

Tested on imx6sx-udoo-neo and imx6sx-sdb boards.
