[PATCH v4 06/17] system/physmem: Pass address space argument to cpu_flush_icache_range()

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

Rename cpu_flush_icache_range() as address_space_flush_icache_range(),
passing an address space by argument. The single caller, rom_reset(),
already operates on an address space. Use it.
