[PATCH v2 1/3] hw/ssi/aspeed_smc: Rename 'max_slaves' variable as 'max_peripherals'

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

In order to use inclusive terminology, rename max_slaves
as max_peripherals.

Patch generated using:

  $ sed -i s/slave/peripheral/ \
        hw/ssi/aspeed_smc.c include/hw/ssi/aspeed_smc.h

One line in aspeed_smc_read() has been manually tweaked
to pass checkpatch.
