result into 64-bit pair of XRF registers.
These instructions stain HI/LO registers with the final result.
Their opcode is close to the MIPS32R1 MADD[U]/MSUB[U], so it have to
call decode_opc_special2_legacy when failing to find MXU opcode.
Moreover, it solves issue with reinventing MUL and malfunction

Loongson introduced CSR instructions since 3A4000, which looks
similar to IOCSR and CPUCFG instructions we seen in LoongArch.
Unfortunately we don't have much document about those instructions,
bit fields of CPUCFG instructions and IOCSR registers can be found
at 3A4000's user manual, while instruction encodings can be found
at arch/mips/include/asm/mach-loongson64/loongson_regs.h from
Linux Kernel.
Our predefined CPUCFG bits are differ from actual 3A4000, since
we can't emulate all CPUCFG features present in 3A4000 for now,
we just enable bits for what we have in TCG.

Previous implementation of MIPS cp0_timer computes a
cp0_count_ns based on input clock. However rounding
error of cp0_count_ns can affect precision of cp0_timer.
Using clock API and a divider for cp0_timer, so we can
use clock_ns_to_ticks/clock_ns_to_ticks to avoid rounding
issue.
Also workaround the situation that in such handler flow:
count = read_c0_count()
write_c0_compare(count)
If timer had not progressed when compare was written, the
interrupt would trigger again.

This commit addresses a bug in the AVR interrupt handling code.
The modification involves replacing the usage of the ctz32 function
with ctz64 to ensure proper handling of interrupts above 33 in the AVR
target.
Previously, timers 3, 4, and 5 interrupts were not functioning correctly
because most of their interrupt vectors are numbered above 33.
