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.
