net: hisilicon: rename CACHE_LINE_MASK to avoid redefinition

Building on ARCH=arc causes a "redefined" warning, so rename this
driver's CACHE_LINE_MASK to avoid the warning.

../drivers/net/ethernet/hisilicon/hip04_eth.c:134: warning: "CACHE_LINE_MASK" redefined
  134 | #define CACHE_LINE_MASK   0x3F
