SYS_HEAPINFO is one of the few semihosting calls which has to write
values back into a parameter block in memory. When we added
support for 64-bit semihosting we updated the code which reads from
the parameter block to read 64-bit words but forgot to change the
code that writes back into the block. Update it to treat the
block as a set of words of the appropriate width for the guest.
