powerpc/udbg: Fix Kconfig entry for avoiding 44x early debug with KVM
It was preventing the global early debug selection whenever KVM was enabled instead of only preventing the 440 specific one. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Select this to enable early debugging for IBM 44x chips via the
inbuilt serial port. If you enable this, ensure you set
