All stable branches: apply fc96ec826bce ("spi: fsl-cpm: Use 16 bit mode for large transfers with even size")

[Christophe Leroy <christophe.leroy@xxxxxxxxxx>]

Hello,

In addition to c20c57d9868d ("spi: fsl-spi: Fix CPM/QE mode Litte 
Endian") that you already applied to all stable branches, could you 
please also apply:

8a5299a1278e ("spi: fsl-spi: Re-organise transfer bits_per_word adaptation")
fc96ec826bce ("spi: fsl-cpm: Use 16 bit mode for large transfers with 
even size")

For 4.14 and 4.19, as prerequisit you will also need

af0e6242909c ("spi: spi-fsl-spi: automatically adapt bits-per-word in 
cpu mode")

Thanks
Christophe
