platform/x86: mlx-platform: Add definitions for new registers
Add definitions for new registers: - CPLD3 version - next generation systems are equipped with three CPLD; - Two reset cause registers, which store the system reset reason (like system failures, upgrade failures and so on; Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>
