iio: pressure: mprls0025pa: fix scan_type struct
[ Upstream commit 8a228e036926f7e57421d750c3724e63f11b808a ]
Fix the scan_type sign and realbits assignment.
The pressure is a 24bit unsigned int between output_min and output_max.
transfer function A: 10% to 90% of 2^24
transfer function B: 2.5% to 22.5% of 2^24
transfer function C: 20% to 80% of 2^24
[MPR_FUNCTION_A] = { .output_min = 1677722, .output_max = 15099494 }
[MPR_FUNCTION_B] = { .output_min = 419430, .output_max = 3774874 }
[MPR_FUNCTION_C] = { .output_min = 3355443, .output_max = 13421773 }
