ENGR00154300-2 ASRC: Fix Mx53 ASRC not works with SSI
Asrc not works with ssi, it partly caused by ASRC driver not correctly
handle ssi input clock and data format.
SSI frame clock counting by word, when data format is 16bit-LE,
two channel data combine to one word, and frame rate used by
ASRC should take this into account.
And more, unlike Mx3x, Mx5x should set input and output data format
correctly in its ASRMCR1x register.
