  hw/mips: Remove the 'r4k' machine

We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.

To repeat the rationale from the deprecation note:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago

Users are recommended to use the Malta board instead.

  hw/intc/loongson: Fix incorrect 'core' calculation in liointc_read/write

According to the loongson spec
(http://www.loongson.cn/uploadfile/cpu/3B1500/Loongson_3B1500_cpu_user_1.pdf)
and the macro definition(#define R_PERCORE_ISR(x) (0x40 + 0x8 * x)), we know
that the ISR size per CORE is 8, so here we need to divide
(addr - R_PERCORE_ISR(0)) by 8, not 4.

  target/mips: Add unaligned access support for MIPS64R6 and Loongson-3

MIPSR6 (not only MIPS32R6) processors support unaligned access in
hardware, so set MO_UNALN in their default_tcg_memop_mask. Btw, new
Loongson-3 (such as Loongson-3A4000) also support unaligned access,
since both old and new Loongson-3 use the same binaries, we can simply
set MO_UNALN for all Loongson-3 processors.
