[PATCH AUTOSEL 6.14 296/642] firmware: arm_ffa: Set dma_mask for ffa devices

[Sasha Levin]

From: Viresh Kumar <viresh.kumar at linaro.org>

[ Upstream commit cc0aac7ca17e0ea3ca84b552fc79f3e86fd07f53 ]

Set dma_mask for FFA devices, otherwise DMA allocation using the device pointer
lead to following warning:

WARNING: CPU: 1 PID: 1 at kernel/dma/mapping.c:597 dma_alloc_attrs+0xe0/0x124
