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.

CM-T54 CoM can be used with various custom baseboards, other than SB-T54 (supplied with SBC-T54 single board computer). Update model property of SBC-T54 DT to clarify this.
