Please, replace EXYNOS5_PA_FIMD with EXYNOS5_PA_FIMD1.

As I mentioned before, Other Exynos5 SoCs can have 2 FIMD IPs.
Also, Exynos5250 uses FIMD1.

As per Joonyoung Shim's comment on my previous patches I renamed it
from EXYNOS5_PA_FIMD1 to EXYNOS5_PA_FIMD. Will change it in next
version.
Thanks for reviewing the patch set.

Let me explain why FIMD1 is right.

Exynos5 SoCs have 2 FIMD IPs, and its address are 0x13800000
And 0x14400000, respectively. Therefore, if address of FIMD IP
Is 0x14400000, it means FIMD1.

Best regards,
Jingoo Han

Best Wishes,
