This patch updates the driver so, in addition to current DT bindings, it
also can also use the new DT bindings with cpu, codec subnodes which allow
to support sound on the HDMI interface.

The new DT bindings are introduced so sound on the HDMI interface
can also be supported. The exisiting CPU and CODEC DAI phandle
properties are marked as deprecated.

The RCLKSRC mux input 0 is a default configuration after reset, so
there is no need for this explicit snd_soc_dai_set_sysclk() call.
Also, this static mux clock configuration can be specified in DT.

As the RCLK clock may be updated through the common clk API before each
snd_soc_dai_ops::trigger call, it is not enough to update i2s->rclk_srcrate
only once after it has been initially set to 0. To avoid wrong PSR values
we always get RCLK frequency from the CLK_I2S_RCLK_SRC clock, when that
clock is available.

The code for dereferencing device nodes in the 'codecs' array is moved
to a separate function so we can avoid open coding that in drivers.

The Odroid boards are manufactured by Hardkernel, not Samsung. New compatible
string entries are added, with "hardkernel," instead of "samsung," vendor
prefix. Support for the old compatible strings is going to be removed after
some time.

The #sound-dai-cells property might be helpful in selecting primary
or secondary CPU DAI and it's already present in i2s nodes for some
exynos SoCs so let's add it to the DT binding documentation.

This patch defines I2S1 - HDMI DAI link and implements related
hw_params callback. The AUD PLL frequency is configured through
the CLK_SCLK_I2S1 leaf clock, the exynos5433 clock tree
definitions are updated in a separate patch.
The device tree parsing part is changed is a way it supports older
DTBs with just a single CPU DAI specified, without the HDMI link.

The SAMSUNG_I2S_OPCLK is not currently used by any card driver thus we can
safely change semantics of 'dir' argument of the I2S set_sysclk() callback.
Now an enumeration is exported instead of directly using register bit field
values.

It seems both PCLK_I2S1 and SCLK_I2S1 clocks need to be enabled before
I2S1 control registers can be accessed on exynos5433. If SCLK clock
is disabled an exception is triggered. To fix this parent clock of
the RCLK_SRC clock is assigned to pri_dai->op_clk so required gate
clock is handled by the runtime PM ops.

In order to support multiple instances of the I2S IP block the platform
device name is prepended to each clock registered by the driver.
The clock-output-names property is now not used, this should not cause
any issues as, for example, CDCLK clock is referenced through DT 'clocks'
property, not by name.
This change allows to have both I2S0 and I2S1 enabled simultaneously
on exynos5433 and working properly when #clock-cells property is specified
in respective DT nodes.
