Hi Samuel,
The sysreset uclass has an option to provide the do_poweroff() function. When that option is enabled, the AXP power drivers should not provide their own definition.
For the AXP305, which is paired with 64-bit systems where TF-A provides PSCI, there is another possible conflict with the PSCI firmware driver. This driver can be enabled even if CONFIG_PSCI_RESET is disabled, so make sure to use the right symbol in the condition.

Not a big fan of adding #ifdef's, but it looks like these implementations of do_poweroff() can eventually be removed, when SYSRESET works everywhere? Or is there a reason we cannot select SYSRESET later on, and would still need do_poweroff from those AXP drivers directly?
