soc/hisilicon: Clean the hbmcache state show sysfs 

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IAKLPG



---------------------------------------

There is no need to provide a extra state_show sysfs to
query the hbm_cache state, we can use the "status" sysfs
interface to query the hbm_cache state.
