[POWERPC] pseries: phyp dump: Disable phyp-dump through boot-var
This adds a kernel command line option "phyp_dump", which takes a 0/1 value for disabling/ enabling phyp_dump at boot time. Kdump can use this on cmdline (phyp_dump=0) to disable phyp-dump during boot when enabling itself. This will ensure only one dumping mechanism is active at any given time.
