[PATCH 15/16] mfd: axp20x: skip of_device_id table when !CONFIG_OF

[Krzysztof Kozlowski]

The driver can match either via ACPI or OF.  Its of_device_id table is
referenced via of_match_ptr() so it will be unused for !CONFIG_OF
builds:

  drivers/mfd/axp20x-i2c.c:60:34: warning: ‘axp20x_i2c_of_match’ defined but 
not used [-Wunused-const-variable=]
