spi: spi-ti-qspi: Fix FLEN and WLEN settings if bits_per_word is overridden
Each transfer can specify 8, 16 or 32 bits per word independently of the default for the device being addressed. However, currently we calculate the number of words in the frame assuming that the word size is the device default. If multiple transfers in the same message have differing bits_per_word, we bitwise-or the different values in the WLEN register field. Fix both of these. Also rename 'frame_length' to 'frame_len_words' to make clear that it's not a byte count like spi_message::frame_length.
