[PATCH] unicode: make array 'token' static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array 'token' on the stack but instead make it
static const. Makes the object code smaller by 234 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
   5371	    272	      0	   5643	   160b	fs/unicode/utf8-core.o

After:
   text	   data	    bss	    dec	    hex	filename
   5041	    368	      0	   5409	   1521	fs/unicode/utf8-core.o

(gcc version 9.2.1, amd64)
