qemu: Fix gl failure from 64b target on 32b host
Data from 64b target is truncated by 32b host. This patch makes type of data buf in host same as target. [YOCTO #2221] got fixed.

1This patch fix GL application failure from 64b target on 32b host
2
364b target produce 64b args buffer, but qemu parse it as 32b and get wrong
4data. To avoid this, the type of args buffer in qemu should be same as target,
5that is, target_phys_addr_t. The only potential issue is that we need copy
6the data in buffer one by one, or else data corruption when 32b/64b for
7target/host combination.
