clk: renesas: r9a09g011: Add PWM clock and reset entries

Browse Source 
Add PWM{8..14} clock and reset entries to CPG driver.

The PWM IP on the RZ/V2M comes with 16 channels, but the ISP has
full control of channels 0 to 7, and channel 15, therefore Linux
is only allowed to use channels 8 to 14.

The PWM channel 15 shares apb clock and reset with PWM{8..14}.
The reset is deasserted by the bootloader/ISP.

Add PWM{8..14} clocks to CPG driver and mark apb clock as
critical clock, so that the apb clock will be always on.
