Introduce a new build option CM3_SYSTEM_RESET for A3700 platform, which,
when enabled, adds code to the PSCI reset handler to try to do system
reset by the WTMI firmware running on the Cortex-M3 secure coprocessor.
(This function is exposed via the mailbox interface.)
The reason is that the Turris MOX board has a HW bug which causes reset
to hang unpredictably. This issue can be solved by putting the board in
a specific state before reset.
