[PATCH v3 03/14] x86/msr: Rename rdpmcl() to rdpmc()

["Xin Li (Intel)" <xin@zytor.com>]

Now that rdpmc() is gone, i.e. rdpmcl() is the sole PMC read helper,
simply rename rdpmcl() to rdpmc().

Signed-off-by: Xin Li (Intel) <xin@zytor.com>
Acked-by: Dave Hansen <dave.hansen@linux.intel.com>
---

Changes in v3:
*) Explain the reason of the renaming in the changelog (Dave Hansen).
*) Use shorter name rdpmc() instead of rdpmcq() as the name of the
   sole PMC read helper (Sean Christopherson).
