The current code align MAX_IR_ENTRIE with the CONFIG_MAX_PT_IRQ_ENTRIE
roundup to 2^n, there is an issue of the powerof2_roundup to calculate
the macro, and the code style is very ugly when we use macro to fix it.

So this patch move the calculate and define of MAX_IR_ENTRIE to offline
tool.

`1 << value.bit_length()` is simpler and more straightforward.

Need take care about the boundary values:

`0 if value == 0 else (1 << (value - 1).bit_length())`
