I don't have a Exynos3250 manual but I guess 0x330C is also named
PS_HOLD_CONTROL and 0x400 is SWRESET as the other Exynos SoCs.
I wonder if a macro could be used instead of magic numbers or at
least have a comment next to the offset field.
The patch looks good to me though and a comment can be added as
a follow up so:
Will add a comment about register offset next to it.
