6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Benjamin Boortz <[email protected]>

commit 25cb6e9a13123d1039cdc75b446ac52e1ebdc26d upstream.

The driver calls ocelot_regmap_from_resource() via <linux/mfd/ocelot.h>,
which internally uses devm_regmap_init_mmio() and requires REGMAP_MMIO.
The Kconfig entry does not select REGMAP_MMIO, causing a build failure
when no other driver in the config happens to pull in REGMAP_MMIO:

  include/linux/mfd/ocelot.h:34:24: error: implicit declaration of function 'devm_regmap_init_mmio'

Found by randconfig testing on arm64; tinyconfig reproducer below.
