The SuperIO ACPI name was hard-coded to "SIO0". Allow setting the name
in the device tree so more than one SuperIO can be named.
An upcoming board (purism/librem_l1um_v2) has two SuperIOs - one in the
AST2500 BMC, and a Nuvoton NCT6791D used for hardware monitor, POST
display, etc.
Many boards have references to SIO0 already, so the default name is
still the same for a single SuperIO.
