e01aac5353 thermal: sun8i: Use bitmap API instead of open code 
The bitmap_* API is the standard way to access data in the bitfield.
So convert irq_ack to return an unsigned long, and make things to use
bitmap API.

771151bed9 thermal: sun8i: add TEMP_CALIB_MASK for calibration data in sun50i_h6_ths_calibrate 
For sun50i_h6_ths_calibrate(), the data read from nvmem needs a round of
calculation. On the other hand, the newer SOC may store other data in
the space other than 12bit sensor data. Add mask operation to read data
to avoid conversion error.

291292cddc thermal: sun8i: Remove unused variable and unneeded macros 
The cp_ft_flag variable is not used after initialization, so delete
it. After that, THS_EFUSE_CP_FT_MASK, THS_EFUSE_CP_FT_BIT and
THS_CALIBRATION_IN_FT are not needed, so delete them.

69d5f3a9c0 thermal: sun8i: Fix using plain integer as NULL pointer in sun8i_ths_resource_init 
sparse returns a warning:

"drivers/thermal/sun8i_thermal.c:341:60: sparse: sparse: Using plain
integer as NULL pointer".

Fix it by replacing the zero integer by a NULL pointer.
