[Intel-gfx] [PATCH 1/2] drm/i915: stolen_reserved_base is also dma_addr_t

[Paulo Zanoni]

The chunk added by this patch was missed by these commits:
* 920bcd1820a6 ("drm/i915: make i915_stolen_to_physical() return phys_addr_t")
* c88473878d47 ("drm/i915: Treat stolen memory as DMA addresses")

The stolen_reserved_base variable contains a memory address for stolen
memory and our code uses dma_addr_t for pointers to stolen, so it
makes sense to make it also be dma_addr_t. Notice that the local
variable inside i915_gem_init_stolen() that stores this pointer is
even already dma_addr_t.

This change essentially converts the size to 64 bits where applicable,
making sure things work in case we ever get crazy enough to put stolen
that far in memory.
