thermal: ti-soc-thermal: add thermal data for DRA752 chips
This patch adds the thermal data for TI DRA752 chips.
In this change it includes (autogen):
. Register offset definitions
. Bitfields and masks for all registers
. Conversion table
Also, the thermal limits, thresholds and extrapolation
rules are included. The extrapolation rule is simply
add +2C as margin.
All 5 sensors, MPU, GPU, CORE, DSPEVE and IVA, are defined
and exposed. Only MPU has cooling device.
