powerpc/mm/radix: Parse disable_radix commandline correctly.
kernel parameter disable_radix takes different options disable_radix=yes|no|1|0 or just disable_radix. When using the later format we get below error. `Malformed early option 'disable_radix'` Fixes: 1fd6c0220710 ("powerpc/mm: Add a CONFIG option to choose if radix is used by default") Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
