This patch adds support for the "marvell,reg-init" DT property, which is used to describe board specific Marvell PHY register configurations in the board dts file. This DT property is supported in the Linux Kernel since a longer time. Adding it to U-Boot now, enables the boards which describe the register settings in their DT files here as well.
I've included calling this marvell_of_reg_init() to all foo_config() functions in this patch as well. If CONFIG_DM_ETH is not set, there is no ofnode, or no "marvell,reg-init" property, the PHY initialization is unchanged.
The function marvell_of_reg_init() is a port of the Linux version. Please note that I explicitly did not add error checking and handling to the U-Boot version, as this is basically not done for phy_read/write in this Marvell PHY code.
This will be used by the upcoming ethernet support on the MIPS Octeon EBB 7304 board.

I think fdt32_to_cpu() would be better than be32_to_cpup(), but that is just a nitpick.
