Subject: iio: pressure: st_pressure_core: disable multiread by default for LPS22HB

From: Lorenzo Bianconi <[email protected]>

commit add6e6ab3ee0e237822e0951476d3df039b49ec8 upstream.

Set multiread variable to false for LPS22HB pressure sensor since it is already enabled in CTRL_REG2. Previous configuration does not cause any issue in I2C communication since SUB Msb has no meaning whereas it breaks register address in SPI communication

Fixes e039e2f5b4da (iio:st_pressure:initial lps22hb sensor support)
