[PATCH 2/2] input: ti_am33x_tsc: make the documentation for the ti,wire-config parameter clear

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

The document says "first four bits" and means the upper nibble. Most
people would probably agree that the first four bits are bits 0…3 and
that is the lower nibble.
This patch updates the documentation so it is clear what is meant.
