thermal/drivers/rz2gl: Fix OTP Calibration Register values
As per the latest RZ/G2L Hardware User's Manual (Rev.1.10 Apr, 2022),
the bit 31 of TSU OTP Calibration Register(OTPTSUTRIM) indicates
whether bit [11:0] of OTPTSUTRIM is valid or invalid.
This patch updates the code to reflect this change.
