The assigned parent clocks should be normally specified in the consumer
device's DT node, this ensures respective driver always sees correct clock
settings when required.
This patch fixes regression in audio subsystem on Odroid XU3/XU4 boards
that appeared after commits:
commit 647d04f8e0 ("ASoC: samsung: i2s: Ensure the RCLK rate is properly determined")
commit 995e73e55f ("ASoC: samsung: i2s: Fix rclk_srcrate handling")
commit 48279c53fd ("ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1 access")
Without this patch the driver gets wrong clock as the I2S function clock
(op_clk) in probe() and effectively the clock which is finally assigned
from DT is not being enabled/disabled in the runtime resume/suspend ops.
Without the above listed commits the EXYNOS_I2S_BUS clock was always set
as parent of CLK_I2S_RCLK_SRC regardless of DT settings so there was no issue
with not enabled EXYNOS_SCLK_I2S.

This patch adds support for Odroid XU4 audio. The main difference
comparing to Odroid XU3 is a missing on-board audio CODEC, only
HDMI output is supported on Odroid XU4. External CODEC could be
optionally connected to the I2S port connector.

Add Hardkernel Odroid XU4 board Device Tree sources. The board differs
from Odroid XU3 and XU3-Lite by:
1. No green and red LEDs (except standard red power LED).
2. Only two PWM outputs are used (fan and blue LED)
3. No audio codec.
4. Two USB3 ports in host mode (no micro USB3 connector for OTG).
5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514).
6. Additional connector with IO ports (I2S_0, I2C_5).
7. No DisplayPort (like XU3-Lite).
8. No TI INA231 power measurement sensors (like XU3-Lite).
