  Cc: Linus Walleij

This adds the register offsets for pull up/down for the STMPE
1601, 1801 and 24xx expanders. This is used to bias GPIO lines
and keypad lines.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Hi Sam, Lee: I think you should just ACK this so Dmitry can take the
patch series through the input tree, where the registers need to be
used to enable the keypad on the STMPE2401.
