soc/mediatek/mt8189: Correct AUX LDO mask bit definition

Browse source 
Fix the bit definition for RGS_AUX_LDO_EN_READY_MASK in the MT8189
dptx_reg.h file, changing it from BIT(2) to BIT(0). The MT8189 is only
polling BIT(0) status instead of BIT(2). This correction ensures proper
functionality of the AUX LDO readiness check.
