feat(qemu-sbsa): adjust DT memory start address when supporting RME

When RME is enabled on SBSA, the RMM is located at the start of the NS
RAM and the device tree after it. This patch adjust the DT memory start
address so that anyone reading it has an accurate view of the system
configuration.

feat(qemu-sbsa): relocate DT after the RMM when RME is enabled

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.

refactor(qemu-sbsa): move all DT related functions to sbsa_platform.c

Move all DT related functions to file sbsa_platform_dt.c so that clients
other than SIP SVC can use the funtionality. At the same time, make all
functions that don't need outside visibility static.

No change in functionality.
