LDO8 regulator is used for act led and serial cosole power supply. Its DT status is declared as "disabled", however the serial console was functional until Commit 318dbb02b ("regulator: palmas: Fix SMPS enable/disable/is_enabled") wich properly turns off LDO8 on boot. Fix serial cosole power supply (and act led) on boot by turning LDO8 on.
