[PATCH v3 6/8] mach-snapdragon: use SYSRESET_PSCI

[Caleb Connolly]

Capsule updates depend on SYSRESET, which we currently don't select but
instead use a custom reset_cpu() implementation which just calls
psci_reset().

Clean this up, drop our custom function and require PSCI reset.

There are some Qualcomm platforms that either can or do run without PSCI
support, but we didn't handle these properly before anyway.
