Add basic 24 bit mode to the I2S API with a i2s_set_bits() call.By default 16b mode is still used, but if i2s_set_bits(24) is runbefore i2s_begin() then the HW will drive 24-bits of data. Thisdata must be left-aligned (i.e. bits 31..8) in 4-byte samples.

Add basic 24 bit mode to the I2S API with a i2s_set_bits() call.
By default 16b mode is still used, but if i2s_set_bits(24) is run
before i2s_begin() then the HW will drive 24-bits of data. This
data must be left-aligned (i.e. bits 31..8) in 4-byte samples.
Fixes#5244 (the HW doesn't support 8 or 32 bits, only 16 or 24).
