[PATCH 04/23] irqdomain: Constify parameter in is_fwnode_irqchip()

[Herve Codina <herve.codina@bootlin.com>]

The fwnode parameter has no reason to be pointer to an un-const struct
fwnode_handle. Indeed, struct fwnode_handle is not modified by the
function.

Be consistent with other function performing the same kind
of operation such as is_of_node(), is_acpi_device_node() or
is_software_node(): constify the fwnode parameter.
