fix: a38x, a39x: Add board specific post gpio config callback

	This patch adds to the MV_BOARD_INFO structure an option for a callback
	post GPP configuration.
	(required for upcoming SolidRun ClearFor board support)

This is useful when the user needs to wiggle some gpios after being configured.
For example resetting a phy, switch etc...
