powerpc/mm/hash: Always clear UPRT and Host Radix bits when setting up CPU

Browse source

We will set LPCR with correct value for radix during int. This make sure we
start with a sanitized value of LPCR. In case of kexec, cpus can have LPCR
value based on the previous translation mode we were running.
