Merge tag 'thead-dt-for-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/fustini/linux into soc/dt

T-HEAD Devicetrees for v6.19

Add PWM controlled fan and it's associated thermal management for the
Lichee Pi 4A board.

Enable additional ISA extenstions supported by the T-Head C910 cores:
Zfh, Ziccrse, XTheadvector.

Add reset controllers of more TH1520 subsystems: AP, AO, DSP, MISC, VI.
