[PATCH] mfd: wm8994: Add module description/author/license information

[Peter Robinson <pbrobinson@gmail.com>]

When compiled as a module we get a tainted kernel because of the lack
of the module information and the following errors. Add details to
fix the issue when wm8994_irq/wm8994_regmap are modular.

wm8994_irq: module license 'unspecified' taints kernel.

wm8994_irq: Unknown symbol irq_domain_xlate_twocell (err 0)
wm8994_irq: Unknown symbol regmap_write (err 0)
wm8994_irq: Unknown symbol gpiod_to_irq (err 0)
wm8994_irq: Unknown symbol irq_modify_status (err 0)
wm8994_irq: Unknown symbol irq_set_chip_and_handler_name (err 0)
wm8994_irq: Unknown symbol regmap_add_irq_chip (err 0)
wm8994_irq: Unknown symbol gpiod_get_raw_value_cansleep (err 0)
wm8994_irq: Unknown symbol handle_nested_irq (err 0)
wm8994_irq: Unknown symbol __irq_domain_add (err 0)
wm8994_irq: Unknown symbol irq_create_mapping (err 0)
wm8994_irq: Unknown symbol gpio_to_desc (err 0)
wm8994_irq: Unknown symbol regmap_del_irq_chip (err 0)
wm8994_regmap: module license 'unspecified' taints kernel.
