[PATCH 19/37] it913x: get rid of script loader and and private header file

[Antti Palosaari <crope@iki.fi>]

Used script loader is quite useless and hides register numbers
making code hard to understand. Get rid of it and use standard
RegMap register write functions directly.

it913x_priv.h file leaves empty after that change and is also
removed.
