[PATCH v2] misc: Kconfig: tc9564: fix and simplify dependencies

[Alex Elder]

The TC9564_PCI config option selects PCI_DYNAMIC_OF_NODES.  But that
depends on OF_IRQ, and TC9564_PCI does not satisfy that dependency.
Simply adding "depends on OF_IRQ" results in a recursive Kconfig
dependency, so we need to satisfy it in a different way.

On the other hand, PCI_DYNAMIC_OF_NODES is a user-visible option and
should not be selected.  So switch to depending on that rather than
selecting it.

PCI_DYNAMIC_OF_NODES already depends on OF_IRQ, so we no longer need
to depend on it directly.  OF_IRQ is only exposed as an option if OF
is enabled, so OF_IRQ enabled implies OF is enabled.

Finally, PCI_DYNAMIC_OF_NODES is only exposed as an option if PCI is
enabled, so we can omit the dependency on PCI.

Therefore, depending on (rather than selecting) PCI_DYNAMIC_OF_NODES
satisfies the dependency on OF_IRQ, as well as on OF and PCI.
