[PULL 27/54] hw/arm/armsse: Move sysinfo register block into data-driven framework

[Peter Maydell <peter.maydell@linaro.org>]

Move the sysinfo register block into the data-driven framework.

While we are moving the code for configuring this device around,
regularize on using &error_abortw when setting the integer
properties: they are all simple DEFINE_PROP_UINT32 properties so the
setting can never fail.
