rapidio: change inbound window size type to u64
Current definition of map_inb() mport operations callback uses u32 type
to specify required inbound window (IBW) size. This is limiting factor
because existing hardware - tsi721 and fsl_rio, both support IBW size up
to 16GB.
Changing type of size parameter to u64 to allow IBW size configurations
larger than 4GB.
