Using the 'reboot edl' command in Linux, the platform can reboot to the
Emergency Download mode. Implement the same for U-Boot.
v4: * Update documentation about '-edl' option
* Add API to check for support of PSCI functions
* Check if RESET2 is supported before issuing the command
* Fix compiler warnings
v3: * Introduce a sysreset op that will pass down the 'reset' command
arguments to registered handlers
* Handle 'reset to edl' alone in qcom-psci driver
v2: * Rebased to recent sources
* Dropped the first patch as it is not applicable anymore
* Bind the new driver from psci driver
