[PATCH v2 03/06] input synaptics-rmi4: rmi_f01 - Fix a comment, add a diagnostic message.

[Christopher Heiny <cheiny@synaptics.com>]

In debugging certain touch sensor failures, it's useful to know
whether the device is stuck in bootloader, so print a message
to that effect.

Also, point to the actual location of the defs for the F01 CTRL0
bitfields.
