[Skiboot] [PATCH] opal-prd: Insert powernv_flash module

[Vasant Hegde]

Explictly load powernv_flash module on BMC based system so that we are sure
that flash device is created before starting opal-prd daemon.

Note that I have replaced pnor_available() check with is_fsp_system(). As we
want to load module on BMC system only. Also pnor_init has enough logic to
detect flash device. Hence pnor_available() becomes redundant check.
