spi: Export acpi_spi_find_controller_by_adev()

Browse Source 
Export acpi_spi_find_controller_by_adev() so that ACPI glue code which
wants to dynamically create a spi_device using acpi_spi_device_alloc() or
spi_new_device() on a controller, to which the code does not already have
a reference, can find the controller.
