MLK-16374-3: PxP: improve stride parameter setting compatible
In pxp lib, the unit of stride parameter is pixel and stride is not equal with width parameter of out buffer in some cases. In order to use latest pxp lib in old version rootfs, PXP_DEVICE_LEGACY macro is used to distinguish pxp drvier version. Because the new pxp driver define a new variable and pxp lib can know this through PXP_DEVICE_LEGACY, and determine if use it.
