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.
