Renesas MSIOF (Clock-Synchronized Serial Interface with FIFO) can work as
both SPI and I2S. Adds MSIOF-I2S driver.
MSIOF-SPI/I2S are using same DT compatible properties.
MSIOF-I2S uses Of-Graph for Audio-Graph-Card/Card2,
MSIOF-SPI doesn't use Of-Graph.

ADG needs its MSTP to use it, and it was handled as "clk_i" before.
R-Car Gen2/Gen3 are using it, but Gen4 doesn't have it.
"clk_i" is not intuitive for ADG MSTP.
Let's enable to use "adg" clock. It can keep compatible with R-Car
Gen2/Gen3 and Gen4.

ASoC: renesas: rsnd: care BRGA/BRGB select in rsnd_adg_clk_enable()
Renesas rsnd related clocks are enabled by rsnd_adg_clk_enable(),
but it doesn't care about BRGA/BRGB selection (It is handled when
SSI was started) (BRGA is used for 44.1kHz lineage, BRGB is used for
48kHz lineage in this driver).
But it should be handled since probe time.
Includes BRGCKR_31 in adg->ckr to handle it since boot time.

ASoC: rsnd: adjust convert rate limitation
Current rsnd driver supports Synchronous SRC Mode, but HW allow to update
rate only within 1% from current rate. Adjust to it.
Becially, this feature is used to fine-tune subtle difference that occur
during sampling rate conversion in SRC. So, it should be called within 1%
margin of rate difference.
If there was difference over 1%, it will apply with 1% increments by using
loop without indicating error message.

ASoC: rsnd: don't indicate warning on rsnd_kctrl_accept_runtime()
rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate
(= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it
(A): "SRC Out Rate Switch"
(B): "SRC Out Rate" // it calls (1)
(A): can be called anytime
(B): can be called only runtime, and will indicate warning if it was used
at non-runtime.
To use runtime convert rate (= Synchronous SRC Mode), user might uses
command in below order.
(X): > amixer set "SRC Out Rate" on
> aplay xxx.wav &
(Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz
(Y): calls B
(X): calls both A and B.
In this case, when user calls (X), it calls both (A) and (B), but it is not
yet start running. So, (B) will indicate warning.
This warning was added by commit b5c088689847 ("ASoC: rsnd: add warning
message to rsnd_kctrl_accept_runtime()"), but the message sounds like the
operation was not correct. Let's update warning message.
The message is very SRC specific, implement it in src.c
