Mark mips_ejtag_fdc_encode() methods switch-case-4 as expecting to
fall through.

This patch fixes the following warning:

drivers/tty/mips_ejtag_fdc.c: In function ‘mips_ejtag_fdc_encode’:
drivers/tty/mips_ejtag_fdc.c:245:13: warning: this statement may fall through [-Wimplicit-fallthrough=]
   word.word &= 0x00ffffff;
   ~~~~~~~~~~^~~~~~~~~~~~~
drivers/tty/mips_ejtag_fdc.c:246:2: note: here
  case 3:
  ^~~~
