ASoC: rt1015: add missing header inclusion

To fix compilation error:

error: implicit declaration of function 'ACPI_PTR'
[-Werror,-Wimplicit-function-declaration]
                .acpi_match_table = ACPI_PTR(rt1015_acpi_match),
		                    ^

Adds the missing header "acpi.h" inclusion and sorts in alphabetical.
