[PATCH v3 1/2] ARM: mvebu: add clock aliases for spi0/spi1 on Dove

[Sebastian Hesselbarth]

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

Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth at gmail.com>

Changelog:
v3:
- add clock alias for Dove's spi0/spi1 devices to allow mvebu-spi
  to remove clk_lookup (Reported by Sascha Hauer)

Note: This should be the last clock aliases added here. I prefer having
a DT clk provider for those clocks instead. Either somebody is quicker
than me, or I will provide one during this or next month.
