The I2S-TDM on Rockchip SoCs only support one data lane for tx and one
data lane for rx, but the codec devices may requires a normal tdm work
with more than one data lane.
Enable the TDM_MULTI_LANES to allow driver works under a higher sample
rate and with more data lanes.
More detail, see the driver patch comment.

For controller which is managed by PD (power-domain),
when PD off, the controller is reset to the default
status, and the FRAC-DIV is a fixed value(1/20).
Once the mclk is enabled, there are some high freq cycle
leak, to fix this issue, we use the pinctrl-idle to
block these cycles until the config has been come back
to the normal state.

Define a protocol specification for SPI slave transmission,
with the following main requirements:
1.ctrl packet with 2B cmd, 2B addr(offset in APP_RAM), 4B data
(usually is the following data packet length);
2.data packet with data;
3.support ctrl packet only for configuration;
4.support ctrl packet witch data packet for IO transmission.
5.spidev_rkslv support SPI_OBJ_APP_RAM_SIZE application buffer
Start the test in master device, like following:
echo read 64 1000 > /dev/spidev_rkmst_misc
Show the application buffer in slave device, like following:
echo appmem 0 256 > ./dev/spidev_rkslv_misc
