The attached patch drops 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
