[PULL 2/4] tcg/tci: Restrict tci_write_reg16() to 64-bit hosts

[Laurent Vivier <laurent@vivier.eu>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Restrict tci_write_reg16() to 64-bit hosts to fix on 32-bit ones:

  [520/1115] Compiling C object libqemu-arm-linux-user.fa.p/tcg_tci.c.o
  FAILED: libqemu-arm-linux-user.fa.p/tcg_tci.c.o
  tcg/tci.c:132:1: error: 'tci_write_reg16' defined but not used [-Werror=unused-function]
   tci_write_reg16(tcg_target_ulong *regs, TCGReg index, uint16_t value)
   ^~~~~~~~~~~~~~~

Fixes: 2f160e0f979 ("tci: Add implementation for INDEX_op_ld16u_i64")
