[PATCH RFC] regmap: Move selecting for REGMAP_MDIO and REGMAP_IRQ

[Andrew Davis]

If either REGMAP_IRQ or REGMAP_MDIO are set then REGMAP is also set.
This then enables the selecting of IRQ_DOMAIN or MDIO_BUS from REGMAP
based on the above two symbols respectively. This makes it very easy
to end up with "circular dependencies".

Instead select the IRQ_DOMAIN or MDIO_BUS from the symbols that make
use of them. This is almost equivalent to before but makes it less
likely to end up with false circular dependency detections.

Sending as RFC as I haven't tested all the possible permutations
on config options right now to make sure this causes no changes,
but wanted to suggest this as a possible solution to the circular
dependency described here[0].
