drivers/i2c/ptn3460: Add early init option
Create Kconfig options and boot state machine callback in ramstage for
an early initialization of the PTN3460 DP-to-LVDS bridge. This allows
showing the bootsplash screen on mainboards utilizing this chip during
the PCI device enumeration.
BUG=none
TEST=Select PTN3460_EARLY_INIT config switch in mainboard Kconfig and
check the log for "Attempting PTN3460 early init" message. If the
board (e.g. siemens/mc_apl7 in this case) is also configured for
showing the bootsplash logo, it should be now visible.
