This patch allow mclk shift around +/- 1 Hz compared to
requested freq.
we could not always achieve the precise freq as required,
e.g. request: 98304000, but got: 98303999
there is no big deal and any side effect on the above case,
so, we allow a tiny shift for mclk.

This patch introduce property 'arm,pl330-mcbufsz-bytes' to
support assign mcbufsz from DT.
And we limit the max value to one PAGE_SIZE. though there
is no limit for the controller.
e.g.
arm,pl330-mcbufsz-bytes = <2048>;

1.Add the judgment of signal loss when use g_dv_timing.
2.Wait for the signal to stabilize before get resolution.

On current code, We check the iddig status to make sure that the id
status is indeed in low level, and then send HOST notification and
power on phy based on this state. But On some Rockchip platforms like
RK3328, the ID Detector pin is not cited, the default state of ID pin
is floating, so the iddig status is always 1 which means in device mode.
To resolve this problem, We need to further check whether usb2phy_reg
structure of utmi_iddig has been initialized or not. If not, We can't
use the iddig status as a judgment condition.

The ddc control is designed to be compatible with the leakage
problem of a Konka TV. However, in actual use, it will lead
to the phenomenon of abnormally low hpd in many TVS.
