riscv: Clean up {qemu,spike}_util

spike_util.h:
 - (LOG_)REGBYTES and STORE are already defined in
   arch/riscv/include/bits.h.
 - TOHOST_CMD, FROMHOST_* are helper macros for the deprecated
   Host-Target Interface (HTIF).

qemu_util.c:
 - mcall_query_memory now uses mprv_write_ulong instead of first
   translating the address and then accessing it normally. Thus,
   translate_address isn't used anymore.
 - Several functions used the deprecated HTIF CSRs mtohost/mfromhost.
   They have mostly been replaced by stub implementations.
 - htif_interrupt and testPrint were unused and have been deleted.

spike_util.c:
 - translate_address and testPrint were unused and have been deleted.

After this commit, spike_util.c and qemu_util.c are exactly the same and
can be moved to a common location.
