  The QEMU virt machine supports APLIC and IMSIC emulation so let's
select APLIC and IMSIC drivers from SOC_VIRT kconfig option.

I'm kinda torn with this as I've been trying to get rid of the selects
from the file in the first place. As Maz seems to have decided that the
SiFive plic driver is really the RISC-V plic driver - is there a reason
not to either:
- select the sifive plic at an arch level, or
- put a "default RISCV" type thing in the driver entry?

Similarly here, should we default the APLIC and IMSIC drivers to enabled
for RISCV rather than using selects?
