ARM: dts: socfpga: drop unsupported cdns,page-size and cdns,block-size

cdns,page-size and cdns,block-size are neither documented nor used by
Linux, so remove them to fix dtbs_check warnings like:

  socfpga_arria5_socdk.dtb: flash@0: Unevaluated properties are not allowed ('cdns,block-size', 'cdns,page-size' were unexpected)
