thermal/drivers/qoriq: Support version 2.1
i.MX93 use TMU version 2.1, which supports:
- TRITSR_TP5(When this field is 1, you must add 0.5 K to the temperature
that TEMP reports. For example, if TEMP is 300 K and TP5=1, then the
final temperature is 300.5 K.)
- Has 16 TTRCR register: Temperature Range Control (TTRCR0 - TTRCR15)
This patch is to add this support.
