The way the PSCI DT update happens currently means we pull in
<asm/armv7.h> everywhere, including on ARMv8 and that in turn brings in
<asm/io.h> for some non-PSCI related things that header needs to deal
with.
To fix this, we rework the hook slightly. A good portion of
arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI
is needed on ARMv8 we can re-use this by and large. So rename the
current hook to psci_update_dt(), move the prototype to <asm/psci.h> and
add an #ifdef that will make re-use later easier.
