input: qcom-hv-haptics: Update sequence of reading STATUS_DATA

Browse Source 
Per HW recommendation, when reading HAP_CFG_STATUS_DATA registers,
MOD_STATUS_XT.SEL need to be written first to select the right mux,
then update MOD_STATUS_SEL register so haptics module can present the
desired status values into STATUS_DATA registers.
