iio: pressure: dps310: fix CFG_REG bit definitions
Driver defines them as BIT(4), BIT(5) and BIT(6). Per datasheet P_SHIFT
is bit 2, FIFO_EN is bit 1 and SPI_MODE is bit 0.
Only P_SHIFT has a user. dps310_set_pres_precision() sets it at
oversampling 16 or above, so with wrong bit the result register is never
shifted and stops matching the scale factor compensation divides by.
in_pressure_input returns -ERANGE at oversampling 16, 32 and 64.
FIFO_EN needed by FIFO support later in this series.
