The 2-bit gates found i.MX and Vybrid SoC support different clock
configuration:
0b00: clk disabled
0b01: clk enabled in RUN mode but disabled in WAIT and STOP mode
0b10: clk enabled in RUN, WAIT and STOP mode (only Vybrid)
0b11: clk enabled in RUN and WAIT mode
For some clocks, we might want to configure different behaviour,
e.g. a memory clock should be on even in STOP mode. Add a new
function imx_clk_gate2_cgr which allow to configure specific
gate values through the cgr_val parameter.

After the cleanup on clock drivers, they are now ready to be moved into
drivers/clk. Let's move them into drivers/clk/imx folder.
