Subject: [RFC] ARM PSCI: Add support for vendor-specific SYSTEM_RESET2

This patch adds support for vendor-specific SYSTEM_RESET2 to support
Qualcomm target use cases of rebooting into a RAM dump download mode. I'm
working on the client driver to use the proposed psci_system_reset2()
function but wanted to get this RFC going for PSCI driver changes.
