Merge branch 'net-enetc-improve-the-interface-for-obtaining-phc_index'

Wei Fang says:

====================
net: enetc: improve the interface for obtaining phc_index

The first patch is to fix the issue that a sleeping function is called
in the context of rcu_read_lock(). The second patch is to use the generic
API instead of the custom API to get phc_index. In addition, the second
patch depends on the first patch to work.
