src/mainboard/siemens: Use PTN3460 chip driver

This patch replaces and cleans up the redundant PTN3460 driver files in
/mainboard/siemens directories by using the now available driver in
src/drivers/i2c/ptn3460 and providing mainboard specific functions to
the driver.

TEST=Display is working on Siemens mainboards (e.g. mc_tcu3, mc_apl1, ...).
