hw/ssi: Rename SSI 'slave' as 'peripheral'
In order to use inclusive terminology, rename SSI 'slave' as
'peripheral', following the specification resolution:
https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names/
Patch created mechanically using:
$ sed -i s/SSISlave/SSIPeripheral/ $(git grep -l SSISlave)
$ sed -i s/SSI_SLAVE/SSI_PERIPHERAL/ $(git grep -l SSI_SLAVE)
$ sed -i s/ssi-slave/ssi-peripheral/ $(git grep -l ssi-slave)
$ sed -i s/ssi_slave/ssi_peripheral/ $(git grep -l ssi_slave)
$ sed -i s/ssi_create_slave/ssi_create_peripheral/ \
$(git grep -l ssi_create_slave)
Then in VMStateDescription vmstate_ssi_peripheral we restored
the "SSISlave" migration stream name (to avoid breaking migration).
Finally the following files have been manually tweaked:
- hw/ssi/pl022.c
- hw/ssi/xilinx_spips.c
