i2c: meson: fix return codes on error
Change meson_i2c_xfer_msg() to return -EREMOTEIO in case of NACK, as done by other drivers. Also, don't change the return error in meson_i2c_xfer(). Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>
