Subject: [PATCH] mtd: spi-nor: don't include linux/mtd/cfi.h from header

The newly added broadcom qspi driver in drivers/spi produces a build
warning when CONFIG_MTD is disabled:

include/linux/mtd/cfi.h:76:2: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]

Since drivers like this one don't actually need the cfi.h header,
we can just remove it from the spi-nor.h file and add it to
the only place that actually needs it.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: fa236a7ef240 ("spi: bcm-qspi: Add Broadcom MSPI driver")
