drivers: net: cpsw: always flush cache of size aligned to PKTALIGN

Browse Source 
cpsw tries to flush dcache which is not in the range of PKTALIGN.
Because of this the following warning comes while flushing:

CACHE: Misaligned operation at range [dffecec0, dffed016]

Fix it by flushing cache of size aligned to PKTALIGN.
