[PATCH 2/2] drivers/irqchip: make irq-renesas-irqc.c explicitly non-modular

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The Kconfig currently controlling compilation of this code is:

drivers/irqchip/Kconfig:config RENESAS_IRQC
drivers/irqchip/Kconfig:        bool

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

While at it, since this is core infrastructural code for the platform,
lets prohibit any unbind actions that would have called the .remove
function, if anyone was unwise enough to try that.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

We don't replace module.h with init.h since the file already has that.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
