ACPI / SPI: Use parent's ACPI_HANDLE() in acpi_register_spi_devices()
The ACPI handle of struct spi_master's dev member should not be set, because this causes that struct spi_master to be associated with the ACPI device node corresponding to its parent as the second "physical_device", which is incorrect (this happens during the registration of struct spi_master). Consequently, acpi_register_spi_devices() should use the ACPI handle of the parent of the struct spi_master it is called for rather than that struct spi_master's ACPI handle (which should be NULL). Make that happen and modify the spi-pxa2xx driver, which currently is the only driver for ACPI-enumerated SPI controller chips, not to set the ACPI handle for the struct spi_master it creates.
