soc/intel/common/block: Share Intel Graphics Device init function

This patch extracts and shares the early_graphics.c::device_init()
function to make it available for other use.

The igd_init() function enables MMIO and port IO of the Intel Graphics
Device and program the Base Address Range 0 according to the
`CONFIG_GFX_GMA_DEFAULT_MMIO' configuration element.

BUG=b:279173035
TEST=No impact on a skolas board using this function
