[PATCH] arm64: zynqmp: Add support for SVD devices

[Michal Simek <michal.simek@xilinx.com>]

SVD (Software Virtual Devices) are using different name which can't be
handled via zynqmp_devices structure. That's why introduce
zynqmp_detect_svd_name() which checks ID code for these devices and show
proper name for them.
