Input: ads7846 - fix unaligned access on 7845

[ Upstream commit 03e2c9c782f721b661a0e42b1b58f394b5298544 ]

req->sample[1] is not naturally aligned at word boundary, and therefore we
should use get_unaligned_be16() when accessing it.

Fixes: 3eac5c7e44f3 ("Input: ads7846 - extend the driver for ads7845 controller support")
