Conor Dooley 592f0a9429 hw/{misc, riscv}: pfsoc: add system controller as unimplemented 
The system controller on PolarFire SoC is access via a mailbox. The
control registers for this mailbox lie in the "IOSCB" region & the
interrupt is cleared via write to the "SYSREG" region. It also has a
QSPI controller, usually connected to a flash chip, that is used for
storing FPGA bitstreams and used for In-Application Programming (IAP).

Linux has an implementation of the system controller, through which the
hwrng is accessed, leading to load/store access faults.

Add the QSPI as unimplemented and a very basic (effectively
unimplemented) version of the system controller's mailbox. Rather than
purely marking the regions as unimplemented, service the mailbox
requests by reporting failures and raising the interrupt so a guest can
better handle the lack of support.
