[PATCH v2 2/2] ASoC: atmel-i2s: Fix I2SC_WS slot width configuration

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

The atmel_i2s_hw_params() function configures the PCM formats
S18_3LE, S20_3LE and S24_3LE, which require a 24-bit I2SC_WS
slot width.

However, ATMEL_I2SC_MR_IWS is missing from the mask passed to
regmap_update_bits() when updating ATMEL_I2SC_MR. As a result,
the IWS bit is never updated, potentially leaving the slot width
at 32 bits.

Add ATMEL_I2SC_MR_IWS to the mask to ensure the slot width is
configured correctly.
