drm/mipi-dbi: align max_chunk to 2 in spi_transfer
In __spi_validate, there's a validation that no partial transfers
are accepted (xfer->len % w_size must be zero). When
max_chunk is not a multiple of bpw (e.g. max_chunk = 65535,
bpw = 16), the transfer will be rejected.
This patch aligns max_chunk to 2 bytes (the maximum value of bpw is 16),
so that no partial transfer will occur.
Fixes: d23d4d4dac01 ("drm/tinydrm: Move tinydrm_spi_transfer()")
