ASoC: rockchip: i2s: Fix NULL pointer dereference when pinctrl is not found
Commit a5450aba737d ("ASoC: rockchip: i2s: switch BCLK to GPIO") switched
BCLK to GPIO functions when probing the i2s bus interface, but missed
adding a check for when devm_pinctrl_get() returns an error. This can lead
to the following NULL pointer dereference on a rockpro64-v2 if there are no
"pinctrl" properties in the i2s device tree node.
Check that i2s->pinctrl is valid before attempting to search for the
bclk_on and bclk_off pinctrl states.
Fixes: a5450aba737d ("ASoC: rockchip: i2s: switch BCLK to GPIO")
