[ Upstream commit 93c0210671d8f3ec2262da703fab93a1497158a8 ]
Left and Right justified mode are computed using the same formula as DSP_A and DSP_B mode. Which is wrong and the user manual explicitly says:
LRCK_PERDIOD: PCM Mode: Number of BCLKs within (Left + Right) channel width. I2S/Left-Justified/Right-Justified Mode: Number of BCLKs within each individual channel width(Left or Right)
Fix this by using the same formula as the I2S mode.
