[PATCH] powercap/drivers/dtpm: Fix __udivdi3 and __aeabi_uldivmod unresolved symbols

[Daniel Lezcano]

32 bits architectures do not support u64 division, so the macro
DIV_ROUND_CLOSEST is not adequate as the compiler will replace the
call to an unexisting function for the platform, leading to an
unresolved symbols.

Fix this by using the compatible macros:

DIV64_U64_ROUND_CLOSEST and DIV_ROUND_CLOSEST_ULL.
