ARM: OMAP: AM43xx hwmod: Add data for am43xx emif hwmod
Without a hwmod for am43xx emif use counting for emif clockdomain does not happen correctly so it may be shut off by pm code unintentionally. Signed-off-by: Dave Gerlach <d-gerlach@ti.com> [paul@pwsan.com: updated to apply] Signed-off-by: Paul Walmsley <paul@pwsan.com>
