Subject: staging: android ion/hisi: fix dependencies

From: Arnd Bergmann <arnd@arndb.de>

commit 4a236d01b5e0d7e6f4ee9e6c4056fce10b38e8ad upstream.

The newly added Hi6220 Ion code fails to build when the ION_OF helpers
are not present:

drivers/staging/android/ion/hisilicon/hi6220_ion.o: In function `hi6220_ion_remove':
hi6220_ion.c:(.text.hi6220_ion_remove+0x4c): undefined reference to `ion_destroy_platform_data'
drivers/staging/android/ion/hisilicon/hi6220_ion.o: In function `hi6220_ion_probe':
hi6220_ion.c:(.text.hi6220_ion_probe+0x5c): undefined reference to `ion_parse_dt'
hi6220_ion.c:(.text.hi6220_ion_probe+0xf8): undefined reference to `ion_destroy_platform_data'

This selects the symbol when needed.
