[U-Boot] [PATCH v3] rockchip: video: mipi: Modify variable type for arm32 compatibility

[Eric Gao]

Some address relevant varibable is defined originally as u64. To
compatible with arm32, this patch change them to uintptr_t type.

Changes in v2:
-Change the address base variable from "uintptr_t *" to "uintptr_t"

Changes in v1:
-Change the address base variable to uintptr_t * type.
