scsi: ufs: ufs-exynos: Make a const array static, makes object smaller

Browse Source 
Don't populate the const array granularity_tbl on the stack but instead
make it static. Makes the object code smaller by 190 bytes:

Before:
   text    data     bss     dec     hex filename
  25563    6908       0   32471    7ed7 ./drivers/scsi/ufs/ufs-exynos.o

After:
   text    data     bss     dec     hex filename
  25213    7068       0   32281    7e19 ./drivers/scsi/ufs/ufs-exynos.o

(gcc version 10.3.0)
