[PATCH] mailbox: qcom-apcs-ipc: use PLATFORM_DEVID_AUTO to register device

[Shawn Guo <shawn.guo@linaro.org>]

On MSM8916, only one qcom-apcs-msm8916-clk device is needed, as there is
only one APCS clock.  However, on MSM8939 three APCS clocks need to be
registered for cluster0 (little cores), cluster1 (big cores) and CCI
(Cache Coherent Interconnect).  That said, we will need to register 3
qcom-apcs-msm8916-clk devices.  Let's use PLATFORM_DEVID_AUTO rather
than PLATFORM_DEVID_NONE for platform_device_register_data() call.
Otherwise, the second APCS clock registration will fail due to duplicate
device name.
