PMI8996 is *almost* the same hardware as PMI8994, say for some annoyances:
- Boards equipped with PMI8996 now have to include pmic-id (which wasn't the case before)
- Different qpnp-ibb-discharge-resistor value (will be addressed after LABIBB is introduced)
- Different inhibit-derating-ua value (will be addressed after BCL is introduced)
- Different ramp_up_step value (will be addressed after [if?] QPNP Flash LED is introduced)
