Similarly to commit f6361c6b3880 ("ARM: S3C24XX: remove separate restart
code"), the platform watchdog reset code can be removed in favor of
a generic watchdog driver which already handles reset.

This allows removal of a bunch of machine code and fixes also W=1
compile warnings:

The generic watchdog-based system reset is not exactly the same as
before.  The previous method had a fallback to soft_restart() which now
is gone.

The commit also removes a FIXME note about calling s3c64xx_clk_init()
inside s3c64xx_init_irq().  No one fixed this since long time and the
note is not meaningful anymore because watchdog part is removed.

Applied.
