regmap: Move selecting for REGMAP_MDIO and REGMAP_IRQ

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.
