Ezkinil: Update thermal table and fan table
Control the fan speed by the temperature read by TEMP_SENSOR_SOC.
thermal_soc: fan_off = 32C, fan_on = 75C
fan_rpm: min = 3200, start = 3200, max = 6000
fan_table:
on off rpm
0 1(32C) 0
9(36C) 1(32C) 3200
21(41C) 16(35C) 3500
28(44C) 29(39C) 3900
37(48C) 42(43C) 4200
47(52C) 55(47C) 4600
56(56C) 68(51C) 5100
72(63C) 84(58C) 5500
