ARM: dts: socfpga: Flag timer clock as pre-reloc

Flag timer clock as DM pre-reloc, so that a timer driver can be used and
it can extract information about it's clock rate using the clock framework.
This patch also moves some of the pre-reloc flags into the core dtsi file,
this is because the timer is not board specific, but rather is used on all
boards.
