Subject: [PATCHv4] clk: ppc-corenet: rename to ppc-qoriq and add CLK_OF_DECLARE support

The IP is shared by PPC and ARM, this renames it to qoriq for better
represention, and this also adds the CLK_OF_DECLARE support for being
initialized by of_clk_init() on ARM.

Signed-off-by: Jingchang Lu <jingchang.lu@...escale.com>

changes in v4:
 remove "corenet" literals omitted in v3 remove.

changes in v3:
 generate the patch with -M -C option

changes in v2:
 rename the driver name to ppc-qoriq.c for shared on PPC and ARM.
