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