[PATCH v2 1/4] arm64, thunder: Add Kconfig option for Cavium Thunder SoC Family

[rric@kernel.org (Robert Richter)]

From: Radha Mohan Chintakuntla <rchintakuntla@cavium.com>

Increase maximum numbers of cpus to 32. This relates to current
maximal possible cpu number. Increasing this to 64 cpus will be a
separate patch not part of this enablement patches.
