[PATCH v1 13/15] mips: octeon: dts/dtsi: Change UART DT node to use clocks property

Stefan Roese sr at denx.de

From: Aaron Williams <awilliams at marvell.com>

We already have a clock driver for MIPS Octeon. This patch changes the
Octeon DT nodes to supply the clock property via the clock driver
instead of using an hard-coded value, which is not correct in all cases.
