Series hw/sh4: Remove the deprecated SHIX machine | expand

Commit Message

Philippe Mathieu-Daudé Sept. 3, 2024, 3:39 p.m. UTC
The TC58128 NAND EEPROM is not user creatable and
needs to be instanciated in the code via tc58128_init().

Only the SHIX machine was using it, and it was removed
in the previous commit. Since the TC58128 has no more
users, remove it too.
