[PATCH v2 21/38] ARM: orion5x: convert to use 'clocks' property for UART controllers

[Thomas Petazzoni]

Until the previous commit, the Orion5x clocks were not described in
the Device Tree. Now that they are described in the Device Tree, we
can replace the manual 'clock-frequency' property in the UART nodes
by a nicer 'clocks' reference in those UART nodes.

This commit consequently removes the 'clock-frequency' property from
the LaCie edmini_v2 board, which is at this point the only Orion5x
board converted to the Device Tree.
