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 They have mostly been replaced by stub implementations.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.
