media: arch: sh: ecovec: Use new renesas-ceu camera driver
SH4 7724 Ecovec platform uses sh_mobile_ceu camera driver, which is now being replaced by a proper V4L2 camera driver named 'renesas-ceu'. Get rid of soc_camera defined components used to register sensor drivers and of platform specific enable/disable routines. Register GPIOs for sensor drivers and declare memory reserved with memblock APIs as dma capable to be used for CEU buffers. While at there re-order include directives to respect alphabetical ordering.
