Suggested title:
config: update for ppc build with meson
Why config/defconfig_ppc_64-power8-linuxapp-gcc is not updated as well
for RTE_MAX_LCORE?

Hi Thomas
I am taking the opportunity to update RTE_MAX_LCORE for future releases
of dpdk. As we are switching to meson builds soon so this is an
appropriate opportunity to update the value and keep in step with the
hardware. Older stable release can continue to use the smaller value
found in deconfig..

I don't understand the logic.
You are updating only the new release.
Some users may use make and others meson.
There is no reason they don't have the same config.

Fair enough, if make will continue to be supported then both methods
need updating. I will resubmit with you suggestions.
