[PATCH -next] mtd: spi-nor: fix artificial warning when CONFIG_MTD_CFI_Ix disable

[Zeng Heng]

When CONFIG_SPI_INTEL is selected without
CONFIG_MTD_CFI_I[1,2,4,8] enabled, it would raise
compile warning as below:

In file included from ./include/linux/mtd/spi-nor.h:10,
                 from drivers/spi/spi-intel.c:13:
./include/linux/mtd/cfi.h:62:2:
error: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]
   62 | #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.
      |  ^~~~~~~

"mtd/cfi.h" is introduced into "mtd/spi-nor.h" by
commit db4745edb282 ("mtd: spi-nor: add SPI NOR manufacturer IDs"),
which was already removed out since from the commit
d3c4bb31bf62 ("mtd: spi-nor: Drop the MFR definitions").

After above, mtd/cfi.h is not more needed by mtd/spi-nor.h,
so detach the dependence.

Fixes: d3c4bb31bf62 ("mtd: spi-nor: Drop the MFR definitions")
Fixes: db4745edb282 ("mtd: spi-nor: add SPI NOR manufacturer IDs")
