The variable `struct platform_cpu_topology topology` must be

fix(qemu): statically allocate bitlocks array

gpt_runtime_init() now takes the bitlock array's address and size as
argument. Rather than reserving space at the end of the L0 GPT for
storing bitlocks, allocate a static array and pass its address to
gpt_runtime_init(). This frees up a little bit of space formerly
reserved for alignment of the GPT.

When RME is enabled, (1) the RMM is installed at the base of system RAM,
(2) the base of the system RAM is shifted upward, after the RMM and (3)
the device tree is relocated to the new system RAM base.

This patch relocates the device tree to the new system RAM base before
the RMM is installed in RAM. From there, other accesses to the device
tree are using the new location.

When RME is enabled the RMM is placed at the bottom of the NS RAM,
meaning that NS_DRAM0_BASE has to be located after that.

This patch disscociates the base of the NS RAM as defined by QEMU by
introducing a new define, PLAT_QEMU_DRAM0_BASE. An offset can be added
to that new define when the software's view of the base memory need to
differ from QEMU.
