[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.

	  Write kernel log output directly into the VGA buffer or to a serial

	  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.

	  Unmap pages from the kernel linear mapping after free_pages().

	  This results in a large slowdown, but helps to find certain types

	  of memory corruptions.
