Subject: [PATCH] spmi: prefix spmi bus device names with "spmi"

Change the format of spmi bus device names from:
  <spmi_bus_number>-<spmi_device_sid>
  Example: 0-01
to this:
  spmi<spmi_bus_number>-<spmi_device_sid>
  Example: spmi0-01

This helps to disambiguate SPMI device regmaps from I2C ones
at /sys/kernel/debug/regmap since I2C devices use a very
similar naming scheme: 0-0000.
