mtd: chips: fixup dependencies, to prevent build error

Commit 4612c715a6ea ("mtd: cfi: deinline large functions") moved some
code into the cfi_util library without creating a new dependency. So we
can get build failures like the following, when CONFIG_MTD_JEDECPROBE=y
and CONFIG_MTD_CFI_UTIL=m.

   drivers/built-in.o: In function `jedec_read_id':
>> jedec_probe.c:(.text+0x187ed8): undefined reference to `cfi_build_cmd_addr'
   drivers/built-in.o: In function `jedec_read_mfr':
>> jedec_probe.c:(.text+0x187f4a): undefined reference to `cfi_build_cmd_addr'
   drivers/built-in.o: In function `jedec_reset':
>> jedec_probe.c:(.text+0x187fe0): undefined reference to `cfi_send_gen_cmd'
>> jedec_probe.c:(.text+0x188004): undefined reference to `cfi_send_gen_cmd'
>> jedec_probe.c:(.text+0x18802b): undefined reference to `cfi_send_gen_cmd'

>> jedec_probe.c:(.text+0x188130): undefined reference to `cfi_build_cmd_addr'
>> jedec_probe.c:(.text+0x18814d): undefined reference to `cfi_build_cmd_addr'

>> jedec_probe.c:(.text+0x1884c0): undefined reference to `cfi_send_gen_cmd'
>> jedec_probe.c:(.text+0x1884e7): undefined reference to `cfi_send_gen_cmd'
   drivers/built-in.o:jedec_probe.c:(.text+0x188511): more undefined references to `cfi_send_gen_cmd' follow
   drivers/built-in.o: In function `jedec_probe_chip':
>> jedec_probe.c:(.text+0x188618): undefined reference to `cfi_build_cmd'

So let's express the dependency properly.
