The MDC clock is divider from APB Clock for rockchip's socs, if it
was from mac_clk, the mdc clk range might not be between the frequency
range 1.0 MHz - 2.5 MHz.

Under the following conditions, phy will be abnormally enabled.
1. HDMI is enabled in uboot.
2. disabled/bridge_is_on/phy.enabled/mc_clkdis were updated to
work when probe.
3. HDMI is disconnected.
4. drm_helper_probe_single_connector_modes update connector->status
to disconnected and power off phy by dw_hdmi_update_power. But the
polled type of HDMI is DRM_CONNECTOR_POLL_HPD, output_poll_execute
will not process this disconnection, and dw_hdmi_bridge_disable is
not called, hdmi->disabled is still false.
5. vop will be switch to Tv encoder, and dclk is 27MHz.
6. HDMI is connected.
7. dw_hdmi_update_power is called in dw_hdmi_irq, for hdmi->disabled
is false, then phy is powered up with parameter of 27MHz, and
bridge_is_on is set to on.
8. VOP switch to HDMI mode, set the new dclk rate.
9. dw_hdmi_bridge_enable is called, but the bridge_is_on is already on,
phy will not set again, still maintain the parameters that do not
conform to the new dclk rate.
This patch introduced an variable initialized to indicate hdmi is
initialized before probe, e.g. uboot. When power off hdmi, initialized
and disabled is updated.

As the HDMI-audio/codec will cause the hang on bootup, the root
cause that kylin get the invalid master clock from i2s.
$cat/sys/kernel/debug/clk/clk_summary
..
i2s_pre 0 0 0 0 0
sclk_i2s 0 0 0 0 0
i2s_clkout 0 0 0 0 0
Since i2s clock selects io input clock by default, but the hardware
didn't supply the clock.
This patch will fix the sclk_i2s's parent on i2s_frac.
As following:

As the cpu frequency is less than 816MHz, the HDMI display maybe
probably cause a flower screen as below log[0]. And Kylin used the rk3036g
series SoCs that the max cpu frequency supported the 1GHz, not 1.2GHz.
In a word, keep the cpu frequency to 1GHz for kylin board.

In order to support the ap6212 module with rockchip wlan driver,
the kylin dts has to change the below for working.
1) We should add the 'supports-sdio' property for mmc tuning,
that's the rockchip private property, not on the upstream.
2) We should add the wifi power control pin and wifi/bt data for dts,
Maybe the history issue, they like the old driver for power
contronlling, the upstream didn't need these for working. we should
remove it in the future.

In rk3036, the voltages of CPU and GPU are controlled by the same
regulator 'vdd_cpu'.
Here, we fix it to 1.25v to ensure that GPU could work well in
development period.
The actual voltage GPU needs might be much lower, and relative to
the frequency GPU runs at. this would be optimized when we implement
GPU DVFS with devfreq.
