Pxa2xx DMA controller is a 32-bit device and it has no knowledge of system's
physical address size, so it should not use target_phys_addr_t in it's state.
Convert variables descr, src and dest from type target_phys_addr_t to uint32_t,
use VMSTATE_UINT32 instead of VMSTATE_UINTTL for these variables.

We can do this safely because:
1) pxa2xx actually has 32-bit physical address size;
2) rest of the code in file never assumes descr, src and dest variables to have
size different from uint32_t;
3) we shouldn't have used VMSTATE_UINTTL in the first place because this macro
is for target_ulong type (which can be different from target_phys_addr_t).
