lib, linux: move linux specific defines to linux/compat.h
- move linux specific defines from usb and video code into linux/compat.h - move common linux specific defines from include/ubi_uboot.h to linux/compat.h - add for new mtd/ubi/ubifs sync new needed linux specific defines to linux/compat.h Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Marek Vasut <marex@denx.de> Cc: Anatolij Gustschin <agust@denx.de> [trini: Add spin_lock_irqsave/spin_unlock_irqrestore dummies from usb/lin_gadet_compat.h] Signed-off-by: Tom Rini <trini@ti.com>
