Subject: [PATCH 0/2] Support for I/O width within ARM SCMI SHMEM

We just got our hands on hardware that only supports 32-bit access width
to the SRAM being used. This patch series adds support for the
'reg-io-width' property and allows us to specify the exact access width
that the SRAM supports.

Thanks!
