mailbox: exynos: Add support for Exynos850 mailbox

Browse source

Exynos850-based platforms support ACPM and has similar workflow
of communicating with ACPM via mailbox, however mailbox controller
registers are located at different offsets and writes/reads could be
different. To distinguish between such different behaviours,
the registers offsets for Exynos850 and the platform-specific data
structs are introduced and configuration is described in such structs
for gs101 and exynos850 based SoCs. Probe routine now selects the
corresponding platform-specific data via device_get_match_data().
