Since commit 1771afd47430 ("net: cpsw: avoid alignment faults by taking
NET_IP_ALIGN into account") the TI CPSW driver was switched to use correct
define CPSW_HEADROOM_NA to avoid alignment faults, but there are two places
left where CPSW_HEADROOM is still used (without causing issues).

Hence, completely drop CPSW_HEADROOM define and use CPSW_HEADROOM_NA
everywhere to avoid further mistakes in code.
