[PATCH] gpu: host1x: select CONFIG_DMA_SHARED_BUFFER

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Linking fails when dma-buf is disabled:

ld.lld: error: undefined symbol: dma_fence_release
>>> referenced by fence.c
>>>               gpu/host1x/fence.o:(host1x_syncpt_fence_enable_signaling) in archive drivers/built-in.a
>>> referenced by fence.c
>>>               gpu/host1x/fence.o:(host1x_fence_signal) in archive drivers/built-in.a
>>> referenced by fence.c
>>>               gpu/host1x/fence.o:(do_fence_timeout) in archive drivers/built-in.a

Fixes: 687db2207b1b ("gpu: host1x: Add DMA fence implementation")
