Using the 'reboot edl' command in Linux, the platform can reboot to the
Emergency Download mode. Implement the same for U-Boot.

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


Varadarajan Narayanan (3):
  drivers: sysreset: Add sysreset op that can take arguments
  sysreset: Implement PSCI based reset to EDL mode for QCOM SoCs
  configs: qcs9100_defconfig: Enable SYSRESET
