  P2ROUNDUP() and P2ALIGN() macros are buggy when alignment type is smaller
than type of the value to be aligned.

IS_P2ALIGNED() has no the problem since it cast its arugments
to uintptr_t inside, but fixed anyway to follow the same approach as
new EFX_P2ROUNDUP() and EFX_P2ALIGN().

Patches have checkpatches.sh warnings in base driver since space
is required after sizeof.

  net/sfc: fix power of 2 round up when align has smaller type
  net/sfc: fix align to power of 2 when align has smaller type
  net/sfc: unify power of 2 alignment check macro
