[PATCH 1/3] platform: generic: spacemit: k1: rename cache flush operation

[Troy Mitchell]

From: Xianbin Zhu <xianbin.zhu at linux.spacemit.com>

MRAOP_ICACHE_INVALID is used to flush the local D-cache before a hart
stops, so the name incorrectly describes I-cache invalidation. Rename
it to MRAOP_CACHE_FLUSH without changing its encoded value.
