[PATCH 1/2] powerpc/mm/radix: Parse disable_radix commandline correctly.

[Aneesh Kumar K.V]

From: "Aneesh Kumar K.V" <aneesh.kumar at linux.vnet.ibm.com>

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'`
