Add core temperatures for Rockchip RK3588 SoC

[segabor]

My attempt to map SoC core temperatures to virtual cores. Rather a hack than a well reasoned change. There must be a proper way to determine chipset so temperature mapping can be done if condition is met (a refactor will be needed). Also, data[0] is not set. We have two candidates here, center_thermal and soc_thermal values.

SoC Thermal Drivers

sensors utility bundled with lm-sensors package detected the following thermal drivers

npu_thermal-virtual-0
Adapter: Virtual device
temp1:        +35.2 C  

center_thermal-virtual-0
Adapter: Virtual device
temp1:        +35.2 C  

bigcore1_thermal-virtual-0
Adapter: Virtual device
temp1:        +36.1 C  

soc_thermal-virtual-0
Adapter: Virtual device
temp1:        +36.1 C  (crit = +115.0 C)

nvme-pci-0100
Adapter: PCI adapter
Composite:    +41.9 C  (low  =  -0.1 C, high = +71.8 C)
                       (crit = +89.8 C)

gpu_thermal-virtual-0
Adapter: Virtual device
temp1:        +35.2 C  

littlecore_thermal-virtual-0
Adapter: Virtual device
temp1:        +36.1 C  

bigcore0_thermal-virtual-0
Adapter: Virtual device
temp1:        +36.1 C
