mtd: cfi_util: use DIV_ROUND_UP() in cfi_udelay()
Use DIV_ROUND_UP() in cfi_udelay() instead of open-coding it...
Doing this also helpfully gets rid of two complaints from
'scripts/checkpatch.pl --strict':
CHECK: spaces preferred around that '+' (ctx:VxV)
#29: FILE: drivers/mtd/chips/cfi_util.c:29:
+ msleep((us+999)/1000);
^
CHECK: spaces preferred around that '/' (ctx:VxV)
#29: FILE: drivers/mtd/chips/cfi_util.c:29:
+ msleep((us+999)/1000);
