Ashok Reddy Soma 3adc17f60b lib: div64: Add support for round up of div64_u64 
Most of the frequencies are not rounded up to a proper number.
When we need to devide these frequencies to get a number for example
frequency in Mhz, we see it as one less than the actual intended value.
Ex: If we want to get Mhz from frequency 199999994hz, we will calculate
it using div64_u64(199999994, 1000000) and we will get 199Mhz in place
of 200Mhz.

Add a macro DIV64_U64_ROUND_UP for rounding up div64_u64. This is taken
from linux 'commit 68600f623d69("mm: don't miss the last page because of
round-off error")'.
