[PATCH] thermal/drivers/rockchip: add missing rk3328 mapping entry

The mapping table for the rk3328 is missing the entry for -25°C which is
found in the TRM[1] §9.5.2 "Temperature-to-code mapping".

NOTE: the kernel uses the tsadc_q_sel=1'b1 mode which is defined as:
4096-. Whereas the table in the TRM gives the code
"3774" for -25°C, the kernel uses 4096-3774=322.
