ppc/pnv: Remove default disablement of the PNOR contents

On PowerNV systems, the BMC is in charge of mapping the PNOR contents
on the LPC FW address space using the HIOMAP protocol. Under QEMU, we
emulate this behavior and we also add an extra control on the flash
accesses by letting the HIOMAP command handler decide whether the
memory region is accessible or not depending on the firmware requests.

However, this behavior is not compatible with hostboot like firmwares
which need this mapping to be always available. For this reason, the
PNOR memory region is initially disabled for skiboot mode only.

This is badly placed under the LPC model and requires the use of the
machine. Since it doesn't add much, simply remove the initial setting.
The extra control in the HIOMAP command handler will still be performed.
