First RISC-V PR for QEMU 7.2

* Update [m|h]tinst CSR in interrupt handling
* Force disable extensions if priv spec version does not match
* fix shifts shamt value for rv128c
* move zmmul out of the experimental
* virt: pass random seed to fdt
* Add checks for supported extension combinations
* Upgrade OpenSBI to v1.1
* Fix typo and restore Pointer Masking functionality for RISC-V
* Add mask agnostic behaviour (rvv_ma_all_1s) for vector extension
* Add Zihintpause support
* opentitan: bump opentitan version
* microchip_pfsoc: fix kernel panics due to missing peripherals
* Remove additional priv version check for mcountinhibit
* virt machine device tree improvements
* Add xicondops in ISA entry
* Use official extension names for AIA CSRs
