Subject: [PATCH v2] i2c: I2C_HISI should depend on ACPI

The HiSilicon Kunpeng I2C controller driver relies on ACPI to probe for
its presence.  Hence add a dependency on ACPI, to prevent asking the
user about this driver when configuring a kernel without ACPI firmware
support.

Fixes: d62fbdb99a85730a ("i2c: add support for HiSilicon I2C controller")
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

v2:
  - Drop dependency on ARCH_HISI, as this is a public IP which doesn't
    specifically depend on ARCH_HISI.
