Subject: [PATCH] iio: imu: st_lsm6dsx: Fix FIFO diff mask for tagged fifo

From: mario tesi <mario.tesi@...com>

	According to the latest version of datasheet the mask
	for number of unread sensor data in FIFO_STATUS registers
	has been extended to 10 bits

	The devices involved are:
	 - LSM6DSO
	 - LSM6DSOX
	 - ASM330LHH
	 - LSM6DSR
	 - ISM330DHCX
