clk: ppc-corenet: rename driver to clk-qoriq

Freescale introduced new ARM-based socs which using the compatible
clock IP block with PowerPC-based socs'. So this driver can be used
on both platforms.
Updated relevant descriptions and renamed this driver to better
represent its meaning and keep the function of driver untouched.
