[PATCH] frv: drop unsupported debugging features

Drop support for debugging features that aren't supported on FRV:

 (*) EARLY_PRINTK

	The on-chip UARTs are set up early enough that this isn't required,
	and VGA support isn't available. There's also a gdbstub available.

 (*) DEBUG_PAGEALLOC

	This can't be easily be done since we use huge static mappings to
	cover the kernel, not pages.

-         This is useful for kernel debugging when your machine crashes very
-         early before the console code is initialized. For normal operation
-         it is not recommended because it looks ugly and doesn't cooperate
-         with klogd/syslogd or the X server. You should normally N here,
-         unless you want to debug such a crash.
