Add ethernet phy node in at91rm9200ek.dts.
The reg register is not specified, as it may differ depending on the init
process of the board:
ADDR0/1 phy pins are connected to PA13/14 rm9200 pins. Which means the phy
will take its address from these pins during the reset process.

The macb driver will launch a full scan on the mdio bus to discover the phy
address.

This patch prepare the transition to common clk for sama5 dt boards by
replacing the timer init callback.

Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.

In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).

A new function (at91sama5_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.

This patch adds new at91 programmable clocks implementation using common clk
framework.
A programmable clock is a clock which can be exported on a given pin to clock
external devices.
Each programmable clock is given an id (from 0 to 8).
The number of available programmable clocks depends on the SoC you're using.
Programmable clock driver only implements the clock setting (clock rate and
parent setting). It must be chained to a system clock in order to
enable/disable the generated clock.
The PCKX pins used to output the clock signals must be assigned to the
appropriate peripheral (see atmel's datasheets).

This patch adds new at91 peripheral clock implementation using common clk
framework.

Almost all peripherals provided by at91 SoCs need a clock to work properly.
This clock is enabled/disabled using PCER/PCDR resgisters.

Each peripheral is given an id (see atmel's datasheets) which is used to
define and reference peripheral clocks.

Some new SoCs (at91sam9x5 and sama5d3) provide a new register (PCR) where you
can configure the peripheral clock as a division of the master clock.
This will help reducing the peripherals power comsumption.
