[PATCH RESEND] ARM: mvebu: add clock aliases for spi0/spi1 on Dove

This adds clock aliases for spi controllers found on Dove to allow
spi driver to get tclk frequency.

@Sascha: I forgot to update MVEBU SPI v4 patch numbering to indicate
that this patch is also required for the SPI driver to find its clock
with clk_get instead of clk_fixup.

As stated in the original patch for SPI clock aliases, I am not planing
to add any more clk aliases like this but prefer to work on DT clk
provider first.
