The driver detects it
da9063 6-005a: Device detected (chip-ID: 0x61, var-ID: 0x63)
Comparing the datasheets makes it obvious that 9063L is just a cut-down
version of 9063, with less LDOs and one less ADC. So I think we should
have extra compatible and have the driver restrict which LDOs can be
used with this smaller PMIC.
