net/sfc: unify power of 2 alignment check macro
Substitute driver-defined IS_P2ALIGNED() with EFX_IS_P2ALIGNED() defined in libefx. Add type argument and cast value and alignment to one specified type. Fixes: e1b944598579 ("net/sfc: build libefx") Cc: stable@dpdk.org Signed-off-by: Andrew Rybchenko <arybchenko@solarflare.com>
