net: zynq_gem: Use ulong instead of u32 data type

Browse source 
flush_dcache_range() expects unsigned long in the arguments. Here u32
variable is unable to hold the higher address value when ddr mapped
to higher addresses & flushing lower address dchache range instead
which is unmapped causing to crash.
