[PULL 04/20] target/mips: Fix SWM32 handling for microMIPS

[Philippe Mathieu-Daudé]

From: Marcin Nowakowski <marcin.nowakow...@fungible.com>

SWM32 should store a sequence of 32-bit words from the GPRs, but it was
incorrectly coded to store 16-bit words only. As a result, an LWM32 that
usually follows would restore invalid register values.

Fixes: 7dd547e5ab ("target/mips: Use cpu_*_mmuidx_ra instead of
MMU_MODE*_SUFFIX")
